C# Gridview -- How Can I Set Row Focus to the next line in the gridview after updating??

Experts,
I have a C# (.NET - 3.5 Framework) gridview that does EVERYTHING I want, almost ...

I cannot for the life of me figure out how to set the focus to the Next row after a user updates/cancels an update on a row. It just goes back to the top of the gridview... very frustrating.

I can set the focus to the correct line when I edit the gridview (but it shows up at the very bottom of the page). I would like to know how to make it so that the line I am editing in my gridview shows as the first Line in the gridview.

Here is my code to set the focus when editing (qtyOct is an asp:TextBox in an editItemTemplate within the gridview (this works perfectly):
           ((TextBox)gridProg.Rows[e.NewEditIndex].FindControl("qtyOct")).Focus();

 but the same code construct does not work when I try to set the focus after updating the gridview (see attached code) it does not set the focus to the row immediately after the row just updated, it just goes back to the top of the gridview:

In Summary: 2 Questions (which are practially identical):
How can I set the line I am editing to the top of the gridview?
How can I set the line I have just editied to the top of the gridview?

Any help would be greatly appreciated!! Gotta get this into production tonight and this is not crucial, but one could say neither is having dignity ;-)
Thanks one and all!
Dan
         
protected void gridProg_OnRowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        int NextRow = e.RowIndex; //Go to the next row after canceling the update
        gridProg.EditIndex = -1;
        LoadData();
//The following line "should" set the focus to the next line in the gridview -- Instead the gridview loads to the top of the page.
        ((Label)gridProg.Rows[NextRow].FindControl("lblST")).Focus();

    }

You should have any control like textbox, button in next line, so that you can give focus on that.

After updating line a gridview row, you can set the focus on next row using .focus() method of that that control.

I hope you know how you can access the control inside the gridview.

Thanks for the comment VjSoft

Can you give me an example with syntax -- the following syntax works in Edit mode - Not in view mode:

((Label)gridProg.Rows[NextRow].FindControl("lblST")).Focus();

focus on label will not work.

try with a textbox.

((TextBox)gridProg.Rows[NextRow].findcontrol("txtST")).focus();

if you dont want to show textbox on grid, set textbox height to 1 px, backgroud to transparent and its border as flat.

I hope you have links (edit/update/cancel) with each row, you can set focus on any of these links also, whichever is visible in view mode.

Thanks for the solution, but I still do not know how to put the selected row in the gridview at the top of the screen. I will open a new question about that.
