OK,
Im using a grid and wanting to populate it from a SQLDataSource. I set all the sections as needed but nothing populates.
I had a similar problem when populating the Menu from a SQDataSource and had to add
menu1.Datasource = SqlDatSOurce1.Select(DataSourceSelectArguments.Empty)
menu1.DataBind()
to the OnPage_Load event and i did that with this one and still no luck. Is there an issue with the SQLDataSource object and the grid or do i have to specify someting im missing

Hi Loren,
I don't think there is an issue with SqlDataSource or the Grid. Ideally the Grid should support SqlDataSource directly through DataSourceID, but SqlDataSource1.Select should do exactly the same because even if the Grid were to support DataSourceID directly, calling Select and setting the DataSource would be what it does internally.
In order to troubleshoot the problem, first check what Select returns. It supposes to return a DataView or an IDataReader object. If it returns a DataView object, check whether it has any rows by checking its Count property. If it returns an IDataReader (for example, SqlDataReader) object, check whether it has any rows by calling its Read method and then check the return value of Read method. If either case indicates that there are no rows, then the Grid certainly won't populate because it has not been fed any data.
If the data source does have data, you want to check whether the Grid does not render any rows, or renders empty rows with no data. The first case should not happen, but if it does happen, we will be happy to take a look; For the second case it has to do with your DataField setting on each column. When DataField is not correctly set, you will get empty rows but no data.
Thanks

It Returns a Dataview i created a real quick Temp DataView and row count comes back as expect to be 2. how do i set the grid to use the DataView prgramatically i tried DataSource and SourceID but nothing. Sample Code below
Code: Visual Basic.NET
Imports System.Data.SqlClient
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
Dim oDV As Data.DataView
oDV = SqlDataSource1.Select(DataSourceSelectArguments.Empty)
Grid1.DataSourceID = "oDV"
End Sub
End Class

OK i go it to show the Numbers of rows but the Cells and Header are still defaulted. I tried this with an ASP gridView and works so i just need to know how to set the Header and Cells essesntailly
Code: Visual Basic.NET
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure
Dim oDV As Data.DataView
oDV = SqlDataSource1.Select(DataSourceSelectArguments.Empty)
Grid1.DataSource = oDV
Grid1.DataBind()
GridView1.DataSource = oDV
GridView1.DataBind()
End Sub

Hi,
Check the Grid columns' property. There aren't many and you will find your answer very quickly there. :)
Thanks

Hi,
You can take a look of ClientSideOnItemCommand. You can write your own JavaScript handler for that event and when a button is clicked, your handler will be called. You can then do whatever you like to do there.
Thanks
