Say a record has four columns in { Emp#, firstName, secondName, thirdName, spouseName }.
Now if you configure a sql datasource for a dropdownlist to return all columns, only Emp# will be displayed in the dropdownlist, the other columns wont be listed.
Is there a way to list the values of all columns in the dropdownlist using the sql datasource or in ADO.net code.
Thanks.

I have result set as the attached in screenshot, where the candidateid gets duplicated, but then the column university and careerchoice column has different values for the same candidate. (the CareerChoice and University comes from different tables and i have used union clause)
What want is e.g. CandidateId 186 repeats three times, it should be one row, with three columns all filled with the values which are in different rows.
So that I don't have duplicate candidate ids and i have single row with all column data.
If I have this table
Mytable
IdnCol ColumnA ColumnB ColumnC ColumnD
1 CC DD EE FF
2 DD GG HH JJ
3 HH JJ KK HH
How I can check for the repeated value in the column.
for example in the 3rd record, in columnA and ColumnD the value HH is repeated
so is there a way to find if there are values repeated in any of the columnA ColumnB ColumnC ColumnD.
Thanks
May i know what is the SQL query to create another intermediate column which is used to store the sum of two columns of each and every record. Thank you.
View 16 Replies View RelatedI am looking for the best way to check to see if any columns are still NULL in a record. I have a form that gets filled out by users and the values entered into TableA. There are 6 columns in the table, 5 are responses and column6 indicates if the record is complete. So I want a way to see if all of the first 5 columns are NOT NULL and, if so, mark column6 with a 1.
I am thinking this would be a good thing for a trigger on INSERT or UPDATE to check to see if the first 5 columns are filled in and then mark the record as complete.
Although unsupported / undocumented, using FN_DBLOG(..) is inevitable.
While retrieving [RowLog Contents 0]/ [Log Record] transaction log information
I encounter a possible limitation regarding the size of the fetched data.
There is a suspect that data exceeding 8000 bytes is truncated.
I do not manage to get more than 8000 bytes - neither at the Studio Management Query pane nor with a programmatic ODBC piece of code.
There is more data for sure - no doubt about that!!
Does anybody have any idea?

I am looking to create a script that will go through a table a pick out the necessary columns to create a unique record. Some of the tables that I am working with have 200 plus columns and I am not sure if I would have to list every column name in the script or if they could be dynamically referenced. I am working with a SQL server that has little next to no documentation and everytime I type to mere some tables, I get too many rows back.

Hello:I have add a DropDownList to my GridView and binded the dropdownlist to a field from a select statement in the SQLDataSource. I have EnabledEditing for my GridView. The GridView is populated with information from the select statement. Some of the information returned from the select statement is null. The field where the dropdownlist is binded it is null in some cases and does not have a value that is in the dropdownlist so I get and error when I attempt to do an update. 'DropDownList1' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value Is there a way to get around this besides initializing all the columns in the table that are going to be binded to a dropdownlist to a value in the dropdownlist?

Hi,
I have sqldatasource that i set up in VS2005. i have a dropdownlist using this source. Data is added to the db from a different app and i want this dropdownlist to use the latest data on a page refresh.

How is this done.
Thanks.
I'm using the GridView to display some accounting infromation. I have a project where I have a 14 character control number. I would like to have a dropdown list to select the account classification of records to be displayed. The accounting classification is the first two characters of the control number. So the dropdown list needs to show unique first two characters and the GridView will be filtered on these two characters. I have been trying to use "substring" in the ASP.NET code; not even sure you can.
Any suggestions on how to accomplish this would be greatly appreciated. See code below:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2"
DataTextField="control_num" DataValueField="control_num">
</asp:DropDownList><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:GPCRReportsConnectionString %>"
SelectCommand="SELECT DISTINCT [substring(control_num,1,2)] FROM [Request]"></asp:SqlDataSource>
ERROR: Invalid column name 'substring(control_num,1,2)'.

Using asp.net 2.0 and visual studio 2005. The question is regarding the following ER diagram: I've made Firstname, lastname, buildingID and RoomNum all required fields. I've got a modified GridView that displays all of the table Faculty columns. It's been modified so the BuildingID and DepID are resolved to their actual field names and displayed in a DropDownList. In the dropdown list I used for inserting (a seperate DetailsView control), I manually inserted an item into the Department dropdownlist which had the text "-- Select a Department --" with a value of -1. MS SQL didn't like that -1 value so I wrote the following code to fix it: protected void dsFaculty_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
if (e.Command.Parameters["@DeptID"].Value.ToString() == "-1")
{
e.Command.Parameters["@DeptID"].Value = null;
}
} That means of course DeptID is null, which is ok. The problem arises is when I try to edit that row in the GridView. I get the an error 'ddlDepartment' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: valueIdeally, I'd like to make the dropdown list in the GridView show "-- None --" for the DeptID if it comes across a null value. I already tried playing around with the Command.Parameters in the dsFaculty_Selected function, but it didn't work. Ideas?
I am using Visual Studio 2005 & SQL Server. How do i implement a DDL for users to select which value to input. like i can with Access. i do not need a table i think. if not the table would have only ID & Value.?

My goal is to populate a dropdownlist with only with users that are "Techs". I am using the membership database that you ccan set up through VWD. I added this column to the aspnet_Users table: IsTech as bit datatype.

Hi all.
I have a huge problem that ive been sitting with for awhile.
I have a web page with 4 dropdownlist boxes on it
Gender:
Race:
Field:
Location:
Now a user can search a SQL db from selecting values from these 4 dropdownlist boxes which are equal to values in the db obviously.
when they have done that and pressed submit a Gridview is populated with the people corresponding details and the user is able to view each row seperately.
Now the problem i am having is that when i havent used all 4 selections for eg
Gender: null (no value selected)
Race: Black
Field: Accounting
Location: Los Angeles
then no information is returned from the db in the gridview.
im using a sqldatasource to populate the gridview and here is the query string that i am using :
Code:
sql
SELECT [title], [gender], [initials], [name], [surname], [birthdate], [postaladdress], [suburb], [city], [zipcode], [criminalrecord], [drivers], [maritalstatus], [dependants], [citizenship], [province], [contactref], [hometel], [cell], [jobtitle], [relocate], [emmigrate], [email], [worktel], [enddate], [startdate], [FIELD], [education], [company], [positionheld], [jobdescription], [contactperson], [contacttel], [startdate2], [contactperson3], [jobdescription3], [positionheld3], [company3], [enddate3], [startdate3], [contacttel3], [other] FROM [cvinformation] WHERE (([race] = CASE WHEN @race IS NOT NULL THEN @race ELSE [race] END) AND ([province] = CASE WHEN @province IS NOT NULL THEN @province ELSE [province] END) AND ([education] = CASE WHEN @education IS NOT NULL THEN @education ELSE [education] END))
what i want to do is whether the user doesnt choose any selection and leaves the choice null that ALL the information in the table of the db be shown and even if they only choose 2 values and leave the others null then it still brings back the information from the criteria chosen..
Is this possible.?
I have a listbox that lists countries....and if you choose a country, another listbox show cities in that country (fetched from a sql database)....And if you then chose a city in the second listbox, a dropdownlist will show restaurants in the city....(also fetched from a sql-database)...
Ok...I hope you understand...now to the problem....:
If you first chose a country, a city and a restaurant but then want to chose another country in the first listbox, the dropdownlist for the restaurants is still there filled with restaurants for the first country...I dont know how to "remove" the restaurants so that the dropdownlist is blank if someone switch country....
I think I need to do something in countryListbox_SelectedIndexChange....but I dont know what to write there....
I know that I can make the dropdownlist invisible by entering the following code:
sub countryListbox_SelectedIndexChange
dropdownlistRestaurants.visible = false
End sub
But I want it to be visible all the time!
Do you know what I could do?

View 9 Replies View RelatedHey all,
I've been searching for a while and haven't really found an answer for what I'm trying to do. Here it all is and someone can tell me if I'm going in the wrong direction to solve this.
I have a textbox set to a parameter of "SearchString" and a DropDownList with the SelectedValue paramter of "FilterValue". The parameters work, I've tested that. So here is the problem.
I am trying to use the "FilterValue" to pick the field that the "SearchString" searches with a LIKE statement (e.g. SELECT * FROM dbo.Units WHERE (@FilterValue LIKE '%'+@SearchString+'%'))
This, I've found out, doesn't work. I have this setup with a DataLayer.vb in my App_Code directory handling the SQL calls, while the normal CodeBehind is in the typical "Default.vb" page.
I will post code later as I don't have access to it right now, but if anyone can explain how a filter like this would work I would appreciate it!
Thanks,

Hi All,
In my scenario, I am using one sqldatasource with two columns
1. Code_ID
2. Code + ' - ' + CompanyName As Display
Now I bind ddlCompany.datatextfield = Display
ddlCompany.datavaluefield = Code_ID
But the problem is when my CompanyName is NULL value, it does not show my Code too....for example
Code = 1098 CompanyName = NULL
Sql query returns me NULL for this combination....and so my dropdownlist shows blank......can anyone show me the alternative.
Thanking in advance,
