Hi Ramesh, Here it is. In your webform: <asp:datagrid id="DtgTestGrid" Runat="server"
AutoGenerateColumns="False">
<Columns>
<asp:BoundColumn DataField="IDColumn"></asp:BoundColumn>
<asp:TemplateColumn>
<ItemTemplate>
<asp:DropDownList ID="CmbInGrid" Runat="server"
OnSelectedIndexChanged="CmbPostBack_Click" AutoPostBack="True"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:datagrid> In the code behind [I have done it in vb.net] Step 1 Declare
Protected WithEvents CmbTest As System.Web.UI.WebControls.DropDownList Step 2 DataBind
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Handles MyBase.Load
'Put user code to initialize the page here If (Not IsPostBack) Then
ObjDtGrid.Columns.Add("IDColumn") ObjDtRow = ObjDtGrid.NewRow
ObjDtRow(0) = 1
ObjDtGrid.Rows.Add(ObjDtRow) ObjDtRow = ObjDtGrid.NewRow
ObjDtRow(0) = 2
ObjDtGrid.Rows.Add(ObjDtRow) ObjDtRow = ObjDtGrid.NewRow
ObjDtRow(0) = 3
ObjDtGrid.Rows.Add(ObjDtRow) ObjDtRow = ObjDtGrid.NewRow
ObjDtRow(0) = 4
ObjDtGrid.Rows.Add(ObjDtRow)
ObjDtCmb.Columns.Add("CatID")
ObjDtCmb.Columns.Add("CatName") ObjDtRow = ObjDtCmb.NewRow
ObjDtRow(0) = 1
ObjDtRow(1) = "Category 1"
ObjDtCmb.Rows.Add(ObjDtRow) ObjDtRow = ObjDtCmb.NewRow
ObjDtRow(0) = 2
ObjDtRow(1) = "Category 2"
ObjDtCmb.Rows.Add(ObjDtRow) ObjDtRow = ObjDtCmb.NewRow
ObjDtRow(0) = 3
ObjDtRow(1) = "Category 3"
ObjDtCmb.Rows.Add(ObjDtRow) ObjDtRow = ObjDtCmb.NewRow
ObjDtRow(0) = 4
ObjDtRow(1) = "Category 4"
ObjDtCmb.Rows.Add(ObjDtRow) DtgTestGrid.DataSource = ObjDtGrid
DtgTestGrid.DataBind()
End If End Sub Private Sub DtgTestGrid_ItemDataBound(ByVal sender As Object,
ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles
DtgTestGrid.ItemDataBound
Dim ObjCmb As DropDownList
If e.Item.ItemIndex = -1 Then Exit Sub
ObjCmb = e.Item.FindControl("CmbInGrid")
ObjCmb.DataSource = ObjDtCmb
ObjCmb.DataTextField = "CatName"
ObjCmb.DataValueField = "CatID"
ObjCmb.DataBind()
End Sub Step 3 adding event handler
Protected Sub CmbPostBack_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles CmbTest.SelectedIndexChanged
Response.Write(sender.id)
End Sub Now here you will get it posted back. Now the tricky part: Which you
have to do Concentrate on Step 2 how you can make which combo has been clicked in the
datagrid. Cheers Scorp <COLUMNS><ITEMTEMPLATE></ITEMTEMPLATE></COLUMNS>
