0	Hi, You need to define your text box event in design mode in Item Template. Please refer below code: <ItemTemplate> <asp:DropDownList runat="server" ID="ddlCountry" AutoPostBack="true" OnSelectedIndexChanged="General_SelectedIndexChanged" > </asp:DropDownList> </ItemTemplate> Thanks, Manoj Mevada Manoj Mevada Manoj_B, if this helps please login to Mark As Answer. \| Alert Moderator

0	Hi, here is another solution to this problem: You need to remove event binding from design mode and find controls in all rows and bind events after DataBind method of GridView foreach (GridViewRow row in GridView1.Rows) { if (row.RowType == DataControlRowType.DataRow) { ddl = (DropDownList)row.Cells[1].FindControl("ddlCountry"); ddl.SelectedIndexChanged += new EventHandler(General_SelectedIndexChanged); } } Thanks, Manoj Mevada Manoj Mevada Manoj_B, if this helps please login to Mark As Answer. \| Alert Moderator

foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
ddl = (DropDownList)row.Cells[1].FindControl("ddlCountry");
ddl.SelectedIndexChanged += new EventHandler(General_SelectedIndexChanged);
}
}
