Hi,

I have a gridview. In the rowupdating event, the txtbox returns null. I have enabled viewstate for the gridview. But still it does not work. I have made this in Kentico. Please help.


<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"

protected void GridView1_RowUpdating(Object sender, GridViewUpdateEventArgs e)

e.NewValues["name"] = txtbox.Text;
e.NewValues["archived"] = isarchive.Checked;
