Hi

I have a drop down with a repeater control and want to populate it from a value in the database.

I have set the datasource of the repeater and the drop down value is within this datasource

I am using the "Item Created" of the repeater to populate the drop down with values but I don't know how to get it to select a the value from the database. E.g. like

ddlCurrency.Items.FindByText(Utility.BlankIfNull(objReader("firm_funds_managed_currency"))).Selected = True

Any help and code ;) would be great

Try placing this in the ItemDataBound event of the repeater

ddlCurrency.Items.FindByText(Utility.BlankIfNull(objReader("firm_funds_managed_currency"))).Selected = True

I got a" Invalid attempt to read when no data is present"
when i put code below:



Protected Sub parentRepeater_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles parentRepeater.ItemDataBound
		Dim objReader As SqlDataReader = DataAccess.ReaderFromSP("EXEC sp_g_GP_Profile " & Request.QueryString("FirmID"))
		Dim ddlBoard As DropDownList = CType(e.Item.FindControl("ddlBoard"), DropDownList)
		ddlBoard.Items.FindByText(Utility.BlankIfNull(objReader("Board_Rep"))).Selected = True
 
	End Sub
 
	Private Sub Repeater()
'populate repeater and call from Page_load
		Dim objReader As SqlDataReader = DataAccess.ReaderFromSP("EXEC sp_g_GP_Profile " & Request.QueryString("FirmID"))
	
		parentRepeater.DataSource = objReader
		parentRepeater.DataBind()
		objReader.Close()
		
	End Sub

If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then

//........... Write code here

End If

Is it always the same data?  If that is the case, just use a LInqDataSource or SqlDataSource and set the DDL DataSourceID... no code needed.
<asp:Repeater ... >
  <ItemTemplate>
    <asp:DropDownList DataSourceID="lds" ... />
  </ItemTemplate>
</asp:Repeater>
 
<asp:LinqDataSource id="lds" ... />
