How to get Radgrid dropdown list template column selected value in InsertCommand?

I used below, doesn't work. Also, how to make the text filter work for a dropdownlist column?

DropDownList dl;

dl = newItem[

"Language"].Controls[0] as DropDownList;

String SelectLanguageID = dl.SelectedValue;

----------------------------------------------------------------
<telerik:GridTemplateColumn HeaderText="Language" UniqueName="Language"

AutoPostBackOnFilter="true" CurrentFilterFunction="Contains"

ShowFilterIcon="false" FilterControlWidth="200px" >

<asp:DropDownList ID="ddlLanguage" runat="server">

</asp:DropDownList>

</EditItemTemplate>

<asp:Label ID="lblLanguage" runat="server">

</asp:Label>

</FooterTemplate>

</ItemTemplate>

</telerik:GridTemplateColumn>

Thanks!

better?

I know how to do it in code behind - I do all my IO in code - but that isn't what the poster is asking

anyway - to do it in code behind
on an ItemCommand event
if e.CommandName is "PerformInsert"
cast e.Item as GridDataItem
cast e.item("unique name").Controls(0) as RadComboBox (I used a Rad Combo Box, not a drop down list)
the rad combo box selected value I passed into the insert method

hope that helps

Hi Jayesh Goyani,

I converted the code to VB but it doesn´t work, can you tell me why?
In New (), it tells me "Type Expected"!

Dim data As dynamic = New () {
New With { Key .ID = 1, Key .Name = "Name1" },
New With { Key .ID = 2, Key .Name = "Name2" },
New With { Key .ID = 3, Key .Name = "Name3" },
New With { Key .ID = 4, Key .Name = "Name4" },
New With { Key .ID = 5, Key .Name = "Name5" }}
DropDownList1.DataSource = data

Thank you,
João
