[Solved] Accessing Dropdown list on "Edit" ItemCommand

[Richard]

Hello

How do I access a Dropdown List in "Edit" ItemCommand mode?  I need to do something with the control but I am having problems finding it.

	<telerik:GridTemplateColumn HeaderText="Group" UniqueName="tcGroup" Visible="False">
	<EditItemTemplate>
	<asp:DropDownList ID="ddlGroupID" runat="server" DataSourceID="sdsVL_Groups" DataTextField="Name"
	DataValueField="GroupID" SelectedValue='<%# Bind("GroupID_FK") %>' AppendDataBoundItems="True">
	<asp:ListItem></asp:ListItem>
	</asp:DropDownList>
	</EditItemTemplate>
	</telerik:GridTemplateColumn>

	Private Sub rgResource_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles rgResource.ItemCommand
	Select Case e.CommandName
	Case "Edit"
	' REMOVE THE BLANK LISTITEM FROM THE DROPDOWLIST
	End Select

I am trying to remove the blank listitem from dropdown once it goes into Edit mode.  The blank element is there for the "Add New Record" "bug when bound to a datasource".

Thanks

I found an alternative way to achieve this which is to do it during ItemCreated:

Distinguish edit/insert mode on ItemCreated/ItemDataBound:

But still, if there is a way of accessing controls in Edit mode I would be very much interested.

Hello Richard,

Try accessing the dropdownlist in ItemDataBound event instead of ItemComand.

VB:

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then
        Dim dataItem As GridDataItem = TryCast(e.Item, GridDataItem)
        Dim dropdown As DropDownList = DirectCast(dataItem("tcGroup").FindControl("ddlGroupID"), DropDownList)
    End If
End Sub

Thanks,
Princy.
