Can you tell me why are you redirecting the page using "Response.Redirect("../Forms/MyList.aspx")"? Is it the same page or another page?

HI,

If the page is MyList.aspx page then you need not to redirect the page again and again. Just make sure the grid binding in a separate function and call the function/bind the grid in place of

Response.Redirect("../Forms/MyList.aspx");

This will resolve your problem.

[Edit]

If you want to delete a row from the grid then use the following code.

C#

if (e.CommandName == "Delete")
    {
        int index = Convert.ToInt32(e.CommandArgument);
        GridView1.DeleteRow(index);
        ((DataTable)ViewState["DataTable"]).Rows[index].Delete();
        ((DataTable)ViewState["DataTable"]).AcceptChanges();
        GridView1.DataSource = (DataTable)ViewState["Data"];
        GridView1.DataBind();
    }

In this way you can delete a single row.

[/Edit]

Thanks
