Help!!! Gridview Binding

Mar 20, 2008

Hey guys, Am in need of help please, basically the program im working with at the moment is when you add a New Contract, it will grab the Contract Number you have entered, Post it over to another page, then using that number bind a Gridview. The SQL being "SELECT Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent FROM ECS_Contracts_Test WHERE Contract_Number = " & conNoVar (this being the Contract Number of the recently added Contract), however then it comes to Bind the Grid it kicks up an System.Data.SqlClient.SqlException: Syntax error converting the nvarchar value
'2009P7899' to a column of data type int.But the Column Contract_Number is set to Varchar and all I really want to do is to create this gridview using this criteria and not convert anything! The Contract_ID is an int, which is needed as I increment it. Heres the error code:   Public Sub BindtheGrid()'Bind the Contract Grid, where ContractID is used
Dim SQL As String = "Contract_ID, Contract_Number, Start_Date, End_Date, Quarterly_Rent"
Dim objConn As SqlConnection = New SqlConnection(ConnectionString)
Dim cmdstock As SqlCommand = New SqlCommand("SELECT " & SQL & " FROM ECS_Contracts_Test WHERE Contract_Number = " & contractQueryID, objConn)
cmdstock.CommandType = CommandType.Text
objConn.Open()
GridView1.DataSource = cmdstock.ExecuteReader()
GridView1.DataBind()
objConn.Close()
End Sub If you need any more information then please let me know. Mucho Aprreciated

Binding Gridview From Two Different Tables

Jul 30, 2007

Hi all,
The Scenario:
Database1:Table1(callingPartyNumber,originalCalledPartyNumber, finalCalledPartyNumber, DateTimeConnect, DateTimeDisconnect, Duration)
Database2:Table2(Name,Number)
Output in Gridview:




callingPartyNumber
Name
originalCalledPartyNumber
finalcalledPartyNumber
dateTimeConnected
dateTimeDisconnected
Duration (HH:MM:SS)
I bind gridview programatically using DataTable and stored procedures. The data comes from a table (Table1) in a database (Database1) on SQL Server. The gridview displays fields callingPartyNumber, originalCalledPartyNumber, finalCalledPartyNumber, DateTimeConnect, DateTimeDisconnect and Duration in this order. All the columns in this gridview are databound columns.
I have another table (Table2) in a seperate SQL Server database (Database2) but on the same server which maps the callingPartNumber value with the name attached with that number. Note that the field names in Table2 are different from the field names in Table1. Is it possible to display the Name field also in the gridview after the first field callingPartyNumber and then the other fields.
Its like data coming from two tables into the gridview.
Thanks

Gridview Binding With SqlConnection Objects...

Jun 19, 2007

Hello All, I am new to data access and
i have got the problem to display the data into the page by binding the gridview with sqlConnection, sqlCommand and sqlDataReader objects.  The actually code is written as:protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{SqlConnection myConnection;
SqlCommand myCommand;SqlDataReader myReader;
myConnection = new SqlConnection();myConnection.ConnectionString = ConfigurationManager.ConnectionStrings["LatteConnectionString"].ConnectionString;
myCommand = new SqlCommand();myCommand.CommandText = "select * from AntiVirusVendors";myCommand.CommandType = CommandType.Text;
myCommand.Connection = myConnection;
myCommand.Connection.Open();myReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
GridView1.DataSource = myReader;
GridView1.DataBind();
myCommand.Dispose();
myConnection.Dispose();
}
 
}
 
and the GridView in html is listed as:
<div>
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
</div>
So the problem is ---> there is nothing shown in the page, no errors no anything.... just the empty page.
Any ideas would be appreciated. Thanks in advance!

Binding A SqlDataSource, To A GridView At Runtime

Mar 8, 2006

Hello
I'm experiencing some problems, binding a SqlDataSource to a GridView.
The following code creates the SqlDataSource:            string strConn = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;            string strProvider = ConfigurationManager.ConnectionStrings["ConnectionString"].ProviderName;                        SqlDataSource ds = new SqlDataSource(strProvider, strConn);            ds.SelectCommand = "SELECT * FROM rammekategori";
Then i bind the SqlDataSource to a GridView:
         GridView1.DataSource = ds;            GridView1.DataBind();
 
ErrorMessage:
Format of the initialization string does not conform to specification starting at index 0.
Exception Details: System.ArgumentException: Format of the initialization string does not conform to specification starting at index 0.Line 24:             GridView1.DataBind();Am i totally off target here? Can it be something about, that you have to set the datasource of the gridview, before the Page_Load event?
 
Thanks - MartinHN

Want Error Message To Appear When No Database Results Were Returned In GridView, Also Other GridView Issues.

Jun 12, 2008

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having.   Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class  I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!

Error About Nested Table Data Binding

Dec 10, 2007

Hi,

Referring to the book "Data Mining with SQL Server 2005" written by ZhaoHui Tang, I created a Mining Structure and a Mining Model with the AMO API after creating Database and Data Access Objects(referred to code lists from 14-1 to 14-6). I added Nested Table by creating a table column and added a key column to the nested table, while the error showed that in my structure the column of the nested table didn't include effective data bindings when processing.

Thanks for any suggestion!

Error While Using Database Procedure In A Gridview Control

Dec 19, 2006

Dear Forum,
I have a gridview control  which is associated to a storedprocedure  with a parameter(Customer Number) to be supplied.  In the Define Custom Statement or stored procedure section  I selected stored procedure and selected the stored procedure.  The Define Parameter window I defaulted the Parameter Source as 'none' and default value as '%'.   In the next screen, I do a test query which retuns the following error
There was an error executing the query.  Please check the syntax of the command and if present, the type and values of the parameters  and ensure that they are correct.
[Error 42000] [Microsoft][ODBC SQL Server Drive][SQL Server] Procedure 'SP_TransactionDetails' expects parameter '@cnum' which was not supplied.
I am using SQL server studio  2005 version2.0. 
But the same procedure, if I use as SQL Statement, it works.
Can somebody help me.
Thanks,

Error Editing Data Records In Gridview When Using Convert Function.

Jan 24, 2008

Hello, i currently have a gridview that is populated with data from a SQLServer datasource. I have put an output mask in the select statement, so the date and time attributes are displayed in the format i prefer them to be in. SELECT PatientNo, ConsultantName, HospitalName, CONVERT (varchar, Date, 101), CONVERT (varchar, Time, 8) FROM [Appointment];
 However when i click the 'edit' link for a record in the gridview, i am unable to edit the date/time attributes and when i click update to confirm any changes to the other attributes, the values in the date/time attributes are emptied. How can i solve this update problem. I'm guessing i need to configure my SQL UPDATE statement, but bit stuck how i do this. Please help!
Thanks,
James

Gridview / SqlDataSource Error - Procedure Or Function &<stored Procedure Name&> Has Too Many Arguments Specified.

Jan 19, 2007

Can someone help me with this issue? I am trying to update a record using a sp. The db table has an identity column. I seem to have set up everything correctly for Gridview and SqlDataSource but have no clue where my additional, phanton arguments are being generated. If I specify a custom statement rather than the stored procedure  in the Data Source configuration wizard I have no problem. But if I use a stored procedure I keep getting the error "Procedure or function <sp name> has too many arguments specified." But thing is, I didn't specify too many parameters, I specified exactly the number of parameters there are. I read through some posts and saw that the gridview datakey fields are automatically passed as parameters, but when I eliminate the ID parameter from the sp, from the SqlDataSource parameters list, or from both (ID is the datakey field for the gridview) and pray that .net somehow knows which record to update -- I still get the error. I'd like a simple solution, please, as I'm really new to this. What is wrong with this picture? Thank you very much for any light you can shed on this.

Inner Select Binding?

as ftm_child ON ftm_parent.ForumTopicMessageID = ftm_child.ParentMessageID
WHERE ftm_parent.ForumTopicID = @ForumTopicID
ORDER BY ftm_parent.CreateDate
See the purple ftm_parent.ForumtopicMessageID.  If I hard-code that to a 2, this works.  With the fieldname there, SQL Server Management Studio says:
Msg 4104, Level 16, State 1, Procedure udForumTopicMessageByForumTopicID, Line 9
The multi-part identifier "ftm_parent.ForumTopicMessageID" could not be bound.
If any experts out there can help me out with this, I'm sure it wouldn't take much to fix.

Or each have its own conection to the source........or drop conects to source and grid

Binding Last Row In Table To A Label

Oct 23, 2007

Hi all. I have a label on my page and I want to bind it to a field in a table. The catch is that I want to bind it to the last row in the table. I think I can use the custom binding, but I don't know how to bind to the last row. Any Suggestions ?
p.s. The page is tied to an SqlDataSource that retrieves the data from the above table.
Thanks in advance.

SqlDataSource And Parameter Binding

Jan 10, 2006

Hi, I am using a SQL DataSource with a few parameters. I need to specify the value of the parameters at run time but I need a custom way to do it as the value needs to be calculated not come from Cookie, Control, Form, Profile, QueryString or Session. Is there a way to bind your own value to these parameters. For instance if I had a variable how would I bind that to the parameter?
At the moment i am doing the following which works but I dont think it is the correct way
dsMyDataSource.SelectParameters["MyParameter"].DefaultValue = MyCalculatedValue;
In previous projects i have added a value to the Session and then bound the parameter value to the session but that doesnt seem like a good solution either.
Thanks for any help you can give.
Martin

Display Data Without Binding

May 26, 2006

Hi All
I am new to VS 2005 and ASP.NET. I used to use Dreamweaver to design but now I am trying VS.
What I want to do is to display data retrieved with a SqlDataSource in a web page. I know how to do it by binding it to the various controls (Grid, DataList, DetailsView, FormView, Repeater.) available but how can I display it without using any of the mentioned (Grid, DataList, DetailsView, FormView, Repeater)?
Any help apprecited.
