How can I maintain the same selected row even after a sort on a DataGridView
with multiple pages?
I have been looking for an example for weeks and still no luck, so help
would be appreciated.

Thanks

As far as I know there's no DataGridView control in ASP.NET. I assume you
mean GridView. You may refer to the following code. If you mean DataGrid
control the logic is similiar. The basic idea is to use PreRender event to
replace the entire row:

bool sorted = false;

protected void GridView1_PreRender(object sender, EventArgs e)
{
if (sorted)
{
var storedselectedrow = Session["selectedrow"] as
GridViewRow;
var replacedrow = Session["replacedrow"] as GridViewRow;
if (storedselectedrow != null)
{
Session["replacedrow"] = this.GridView1.SelectedRow;
int index = this.GridView1.SelectedIndex + 1;//+1
because of sorting header
if (index < this.GridView1.Controls[0].Controls.Count)
{
this.GridView1.Controls[0].Controls.RemoveAt(index);
this.GridView1.Controls[0].Controls.AddAt(index,
storedselectedrow);
}
}
}

}

protected void GridView1_Sorting(object sender,
GridViewSortEventArgs e)
{


var selectedrow= this.GridView1.SelectedRow;
if (selectedrow != null)
{
Session["selectedrow"] = selectedrow;

}
sorted = true;
}

Please let me know whether it works for you can feel free to ask if you
have further questions.
