find controls from emptydatatemplate in gridview

i am using EmptyDataTemplate for entering new data in grid while there is no existing data,but i am not able to find my controls in the EmptyDateTemplate

protected void gvNavigationDtls_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        if (e.CommandName.Equals("EInsert"))
        {
            GridViewRow emptyrow = gvNavigationDtls.Controls[0].Controls[0] as GridViewRow;
            if (((TextBox)emptyrow.FindControl("txtCode")).Text == "")

in page load also i checked by writing following code

gvNavigationDtls.DataBind();
            Control c = gvNavigationDtls.Controls[0].FindControl("txtCode");
            if (c != null)
            {
            }

but c is null,that means i am not able to find control to use it, Please help,Thanks in Advance

For me, the above code does not work. I have to access the empty template and find the control like this:

TextBox tb1 = (TextBox)((System.Web.UI.Control)e.CommandSource).BindingContainer.Controls[0].FindControl("TextBox5");

The bindingcontainer of the "e.commandsource" is a gridviewrow (then, via the quickwatch you should find the container on which apply findcontrol by going deeper in the "controls" members)

Actually, just had this problem and it's really easy to find access the data but it's in the RowDataBound event.

    Protected Sub grdView(sender As Object, e As GridViewRowEventArgs) Handles grdView.RowDataBound
        If e.Row.RowType = DataControlRowType.EmptyDataRow Then
            Dim txt As TextBox = e.Row.FindControl("txtBox")
            txt.Text = "Hey, this works!"
        End If
    End Sub

          TextBox txtCode=(TextBox)gvNavigationDtls.Controls[0].Controls[0].FindControl("txtCode");
          txtCode.Text="Your value";
        }
     }
