I have a DropDownList which gets populated on Edit event of the DataGrid. But on Update event the selected index always gives the first index value even for other selected item.
What could be the problem and the solution for it? The part below is the code used in C#.

<asp:datagrid id="TransferGroupDataGrid" runat="server" OnUpdateCommand="TransferGroupDataGrid_UpdateComma nd" DataKeyField="rec_id" PageSize="25" AllowPaging="True" BorderColor="#DEDFDE" BorderStyle="None" BorderWidth="1px" BackColor="White" CellPadding="4" GridLines="Vertical" AutoGenerateColumns="False" Width="100%" ForeColor="Black" OnPageIndexChanged="TransferGroupDataGrid_PageInde xChanged">
<Columns>
<asp:BoundColumn Visible="False" DataField="new_jamaat_id" ReadOnly="True" HeaderText="New Jamaat ID"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="New Mouze Name">
<ItemTemplate>
    <asp:Label id=Label1 runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.new_jamaat_name") %>'>
    </asp:Label>
</ItemTemplate>
<EditItemTemplate>
    <asp:DropDownList id=JamaatListBox runat="server" DataValueField="jamaat_id" DataTextField="jamaat_name1" DataSource="<%# GetJamaatList() %>">
    </asp:DropDownList>
</EditItemTemplate>
</asp:TemplateColumn>
<asp:EditCommandColumn ButtonType="LinkButton" UpdateText="Update" CancelText="Cancel" EditText="Allot"></asp:EditCommandColumn>
<asp:ButtonColumn Text="Delete" CommandName="Delete"></asp:ButtonColumn>
</Columns>
</asp:datagrid>


protected void TransferGroupDataGrid_UpdateCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
  if(IsPostBack)
   {
    Response.Write(((DropDownList)e.Item.FindControl(" JamaatListBox")).SelectedItem.Value) ;
   }
}

How are you binding the initial data for the grid? In Page_Load?
If so, do you only bind when there is no PostBack? It could be that your initial data is reloaded in the grid upon PostBack. This also causes the drop-down to be rebound to the data, overwriting the selected item in the drop down.

Thanks Imar .. it worked .

Hello,

I have the same problem. Allways the first value in the list is returned in the Update handler on:
((DropDownList)e.Item.FindControl("myDDL")).Select edItem.Text

I put a break in my private void BindData() and it definitely is called after stumbling in the Update handler.

Any ideas?

Can you post the relevant parts of your code? I think that somehow the drop-down is still bound again on PostBack, overwriting its SelectedIndex value....

Cheers,

Hello,
there is no need for binding DropDownList in such situations,if you bind it,your SelectedIndex will reset ....
just for the first PageLoad you should bind your DropDownList somewhere like ItemDataBound event(after binding your DataGrid),
if you want to change the contents of your DropDownList you should again bind it(by knowing that SelectedIndex will reset again)
meanwhile,when you bind your grid your DropDownList will be bound(because it is the child of your datagrid)
also have a look at this :

it might help you more...
