How To Change Column Names In The Grid View Programatically?
Aug 31, 2007
I have consistent column names that load into a grid view. I now need to change the names in the grid view programatically. I was originally trying to get cute with SQL to do this, but I've been told my below solution will not work and I'm better off to do this in the presentation layer. If this is true, remember I'm still wet behind the ears here...how do I do this in vs2005?
Here's my post to the SQL devs to give you an idea what I'm trying to do.
I have a query that grabs fields from a denormalized table. The result is column names Week1, Week2, Week3....Week26. Users want to see the actual date instead of Week#. So I have a table (lkpdatecaptions ) that contains the fields "fldfieldno" and "Fldcaption".
fldfieldno Fldcaption
----------- --------------
11 9/07/2007
12 9/14/2007
13 9/21/2007
So fieldno 11 represent week1 and so on. So my hope is to update the alias with a query like: Select fldcaption from forecast.tlkpdatecaptions
where fldfieldno = 11
That quey returns the value of 9/7/2007 and is the value I need to represent the coumn alias name.
My current query looks like this:
SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS WEEK1,
So can I do something like the following?
SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS (Select forecast.tlkpdatecaptions.fldcaption from forecast.tlkpdatecaptions where fldfieldno = 11), ...
Hello,I have inserted a drop down list in my Edit template of Grid view. This DDL should control the User_ID who is responsible for the Computer being edited. However I want it to display the User Names rather than the user IDs. I have a COMPUTERS and a USERS table. They are related by having User_ID in both. Below is my grid view with the parts i feel relative highlighted in bold:<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Computer_ID" DataSourceID="SqlDataSource1" CellPadding="4" ForeColor="#333333" GridLines="None"> <FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <RowStyle BackColor="#F7F6F3" ForeColor="#333333" /> <Columns> <asp:CommandField ShowEditButton="True"/> <asp:BoundField DataField="Computer_ID" HeaderText="Computer_ID" InsertVisible="False" SortExpression="Computer_ID" ReadOnly="true" /> <asp:BoundField DataField="Computer_Name" HeaderText="Computer Name" SortExpression="Computer_Name"/> <asp:BoundField DataField="Manufacturer" HeaderText="Manufacturer" SortExpression="Manufacturer"/> <asp:TemplateField HeaderText="User Name" SortExpression="Name"> <EditItemTemplate> <asp:DropDownList ID="DDL_Name" runat="server" DataSourceID="SQLDataSource2" DataValueField="User_ID" SelectedValue='<%# Bind("User_ID") %>'></asp:DropDownList> </EditItemTemplate> <ItemTemplate> <asp:Label ID="lblName1" runat="server" Text='<%# Bind("Name") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" /> <SelectedRowStyle BackColor="#E2DED6" Font-Bold="True" ForeColor="#333333" /> <HeaderStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" /> <EditRowStyle BackColor="#999999" /> <AlternatingRowStyle BackColor="White" ForeColor="#284775" /> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=C:AjaxControlToolkitWebSite1App_DataAssetDatabase.mdf;Integrated Security=True;User Instance=True" ProviderName="<%$ ConnectionStrings:AssetDatabaseConnectionString.ProviderName%>" SelectCommand="SELECT * FROM USERS" > </asp:SqlDataSource> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.SQLEXPRESS;AttachDbFilename=C:AjaxControlToolkitWebSite1App_DataAssetDatabase.mdf;Integrated Security=True;User Instance=True" ProviderName="<%$ ConnectionStrings:AssetDatabaseConnectionString.ProviderName%>" SelectCommand="SELECT COMPUTERS.Computer_ID, USERS.User_ID, COMPUTERS.Computer_Name, COMPUTERS.Manufacturer, USERS.Name FROM COMPUTERS INNER JOIN USERS ON COMPUTERS.User_ID = USERS.User_ID" UpdateCommandType="StoredProcedure" UpdateCommand="StoredProcedure1" > <UpdateParameters> <asp:Parameter Name="Computer_ID" Type="Int32" /> <asp:Parameter Name="User_ID" Type="Int32"/> <asp:Parameter Name="Name" Type="String" /> <asp:Parameter Name="Computer_Name" Type="String" /> <asp:Parameter Name="Manufacturer" Type="String" /> </UpdateParameters> </asp:SqlDataSource> <br /> <br /> </form></body></html> THANKS =]
In my report, I need to display column names (and its values) from my dataset, which uses the stored procedure and within it use the PIVOT statement. I cannot use the matrix control in report since I need to add another static column to the right of the matrix, but since that cannot be done ni SQL SSRS 2005, I need to PIVOT it through stored procedure. The parameter passed to stored procedure is the year and it is used for pivot. The statement looks like this:
@sql = 'SELECT * FROM (SELECT YearId, SchoolId, ReportText, OutputValue_Text from AggregateTable) AS AGAM PIVOT (MIN(OutputValue_Text) FOR YearId IN ([' + @YearId + '])) PVT'
EXEC(@sql)
So, since the years passed as parameters can change, I cannot hard-code it as column in my report, so I need to programatically display column names and values from my dataset, something like dataSet.Tables[0].Columns[].ColumnName; I have tried with writing the code, but I do not have much experience with it and I have not been very successful. Can someone help me with the code?
I have a table of results for various measured quantites and i need to turn this into a view. Only problem is i need to seperate the measured quantities and their respective values into seperate columns.
In SQL 2005 - when I display the results of a View and Copy all rows and columns, the resulting Paste in Excel does not include the column names.
How can I set SQL 2005 so the names of the columns will come along with the content of the copy function?
Background:
When I am using a SQL Query (instead of a view) I have the ability to control whether or not I am able to Include the Column Headers when copying or saving results. The control exists in the Options > Query Results > Results to Grid > Include column headings etc.
My question is how to get this same ability when attempting to copy the results of a VIEW vs. a Query.
Hi, I have a SP which returns a select query on a temp table so I get to choose column names when I create the #table.
Can I determine column names myself based on the results of another query (in the SP) before, or (preferably) after I create the #table and populate it.
My query is used to bind to a datagrid so I could use....
dataGrid.Columns[index].HeaderText and set it to a particular output parameter, but I want to keep the code in the SQL.
We are using UnPivot task to convert the columns into rows using the Excel File as source. But the Excel file column names are changing frequenly sometimes its having only 4 columns sometimes its 10 columns.
Everytime we are checking and unchecking the column list in Unpivot Task.
can anybody help us to solve this issue that Unpivot task should take the column name dynamically.
Hi,I'm trying to create views on all my existing tables and for that I'dlike to create a script or so.I don't want to specify the '*' for the columns in the create viewstatement. I prefer to specify the column names.I have the column names int sys.columns table but Do not know how tohandle them to have a statement like that:CREATE VIEW myVIEWWITH SCHEMABINDINGASSELECT col1name, col2name, col3name, etc...from sys.columns....?????.....Anyone can help?thx,Chris

My question is how to get this same ability when attempting to copy the results of a VIEW vs. a Query. The idea is that when I setup a view it€™s a drag/drop type of query building (query building for dummies if you will). Once I have a view and click the Execute icon it will return all the records selected by the View. However, when I click the upper left/top box to select all rows and column and then try to copy/paste the records into Excel all the data copies just fine but the field name/column headers are not there. How can I get the header fieldname date to copy/paste from View result set that I'm able to copy from a Query result set? Thank you, Mike
for debug purposes i tried to copy paste some Query Analyser output into Excel... the data pastes fine, but i can't get the field-names to copy/paste. is there a trick? izy
Is there a way we can programatically create a SQL server Alias name (SQL 2005 - SQL Native client configuration) using either T-SQL, C# etc. - Manmeet
hi, i have done some testing and its only when i put a grid view or any other type of data viewer on the page, and then connect it to the sql datasource that i get an error Line 1: Incorrect syntax near ')'. now i really cant figure out what it is, here is the code i am using SQL data source code : asp:SqlDataSource ID="SQLDS_view_one_wish" runat="server" ConnectionString="<%$ ConnectionStrings:wishbank_DBCS %>" SelectCommand="SELECT [msg], [Date_Time] FROM [tbl_MSG] WHERE (([Activated] = @Activated) AND ([msgID = @msgID]) )ORDER BY [Date_Time] DESC"> <SelectParameters> <asp:Parameter DefaultValue="Y" Name="Activated" Type="String" /> <asp:SessionParameter Name="msgID" SessionField="sWV" Type="String" /> </SelectParameters> </asp:SqlDataSource>
session variable code which sends it to this page protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { GridViewRow row = GridView1.SelectedRow; Session["sWV"] = row.Cells[1].Text; Response.Redirect("www/viewwf.aspx"); }
if you have an idea please let me know as im stuck!
Inside my gridview, the user can key in new record, delete record and update record. but dont know why my insert function cant work out and i dunno why this is happen? Can somebody help me out with this?Thanks My Code:<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"InsertCommand="INSERT INTO [rest_info] ([resname], [menu], [price], [date]) VALUES (@resname, @menu, @date, @price)"<InsertParameters> <asp:Parameter Name="resname" Type="Char" /> <asp:Parameter Name="menu" Type="char" /> <asp:Parameter Name="price" Type="Decimal" /> <asp:Parameter Name="date" Type="datetime" /> </InsertParameters></asp:SqlDataSource>
i seem to have problems with my grid view not displaying anything when if i test my SQLDataSource, it shows me rows of data.i seem to have this problem only with my Stored procedure, or when i change my Database structure, like add fieldsHere is my procedure: can i do this? select a row and also return a varchar?ALTER PROCEDURE dbo.SelectUpload ( @FileName varchar(50), @Return varchar(MAX) = NULL OUTPUT ) AS SELECT * FROM Uploads WHERE FileName = @FileName

Hi all,I asked a similar question a few weeks ago but I didn't explain myself to well so I was hoping for some more input.I have created a webpage in Visual web developer that contains a gridview that points to an SQL table.All works well as far as searching the table and sorting. The SQL table itself is Droped ( deleted ) and then re-created every 1 minute from a query to a linked DB2 database so that we have a "live" table of our DB2 system but in SQL.....However,There is now a requirement to be able to ADD data to this SQL table. eg: a comments field.. from the website.My procedure for re-creating the SQL DB is now useless as any data added through the website would be lost when the table gets re-created.What is the best way for me to achieve a permanent table in SQL that gets updated from the Linked server DB2 but that I can also add comments from the front end (Website Gridview)..I'm assuming some sort of update query and a join to a seperate, permanent table that contains the comments?.Please help. Ray..
hiii, i am using asp.net 2005 and sql server 2005...i hav a page in which i have used gridview and sql data source..i have written the update command for the same..the problem is when i add the where clause in the query i get an error ,,,,here is the code

I have a list box populated by a SqlDataSource with a basic statement of Select name where location = @location. Location is bound to a dropdownlist control. I want to have a checkbox for the Location dropdownlist and a checkbox for another dropdownlist (for the alphabet) that will select only those people with a last name of the letter selected. Changing the checkbox would change the sql statement. OK so there are two questions here: 1. How can I write a sql statement that would select only people whos last name begins with a certain letter. Would it use some sort of convert function to a string with only 1 letter? 2. How can I programatically change the sqlDataSource's 'select' statement. I need to switch between sorting by location and sorting by alphabetical last name. All of my previous experience has had me configuring the datasource in the asp.net code.
I have gridview bound with SqlDataSource control. One of the grid columns is a dropdown list which is populated programatically, (the gridview has template column with edittemplate field with dropdown list), dropdown Value contains of course collection of IDs.Please tell me how to declare UpdateCommand which will update the row with the dropdown list. The problem is with parameter regarding the column with dropdown list. When i declare this parameter and bind it to SelectedValue property of the dropdownlist from edittemplate tag - it doesnt work, because datasource control cannot see this dropdown list. So, how am i supposed to declare the ID of the row being updated in <updateParameters>? Thanks in advance!
Hi there. I looked through many other posts describing scope_identity but I am trying to achieve the same thing from the code behind. i.e. I need to some how call a method to execute the insert command and then return the ID so I can update other tables with this value. I was going down the road of something like: addnew as sqldatasource = new sqldatasource addnew.insertcommand = "Insert into....; def @NewID as scope_identity" addnew.insert()
The problem is I don't know how to add a output parameter using VB or how to retrieve it. Any help would be much appreciated, this is doing my head in.... Doug.
I am looking for a way to create a stored procedure that will show inventory availability. I would like to show the Inventory Name, The Date, and if the inventory is "checked out" using the ID name of the person who has the item.
For example it would look like this:
-------------------------------------------------------------------------------------------------- Inventory Name | 10/24/2015 | 10/25/2015 | 10/26/2015 | 10/27/2015 | 10/28/2015 -------------------------------------------------------------------------------------------------- Laptop | Tom | Tom | Tom | Avail | Avail Projector | Avail | Avail | Avail | Avail | Bob Air Card | Bob | Bob | Bob | Bob | Bob
It seems like I want to do a pivot table but there really is no aggregate so I am not sure what to use.

hi,i have an sql database on my server on the world wide web.i can make a connection to the database in visual web developer and all the tables etc are shown in the 'database explorer' of visual web developerwhen i make the query in visual web developer it does retrieve the data froom the remote server database when i 'test query'.... so looking great!the connection string in the webconfig file is left as the default when i run the prgram on my LOCAL HOST with the inbult server that comes with visual web developer it runs fine......so.....running on my local pc it will connect to the database on my www host server and does display the data from that database.i need to change the webconfig files path to the connection by default it is |DataDirectory|if i change this to the path i suspect is correct as this is the connection i use to the database C:Inetpubvhostsarcvillage.comhttpdocsApp_DataTestdatabase.mdfwhen i change the path in webconfig then it stops working on my localhost and the error when i ftp it to my host is:Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. Please make sure the user has a local user profile on the computer. The connection will be closed. any ideas?
Wanted to enquire how this is done. Tried doing it in the setUsageType method I have overwritten but only allows description to be changed. Basically need to change "Name".
Best option would be to change it instantly when a user selects a column from the inputs in the custom component, ie. it changes the Output Alias to a desired value. (Input tab in advanced editor)
All this is being done in a custom component which I would like to be synchronous, can achieve a similar result asynchronously.
I have the membership stuff up and running. I've added a field to the membership table called custnmbr. Once a user logs in, I want store his custnbmr in the session and use that to lookup data in another db. ie: Joe logs in and his custnumbr is 001, he goes to the login success page and sees his list of service calls which is: select top 10 * from svc00200 where custnmbr = 001 (the membership.custnmbr for the logged in user) I know how to do this in old ASP using session variables....but I have no idea where to even start with .Net. Many thanks
I was wondering if anyone has an idea of how we could find the table names and column names of the tables in our Sql server database at runtime/dynamically given our connection string? Please let me know.
