Hi..
When I set the SelectedItem... it does not change... any ideas... thanks

I'm trying to find a specific item in grid and set that item to the SelectedItem..      Is the following code the correct method...?
The object is found but the selecteditem does not get set.

   List<inv_mstr> lstFind = this.grid.ItemsSource as List<inv_mstr>;

 

                List<inv_mstr> lstFind2 = (lstFind.Where(i => i.inv_no == Convert.ToInt32(sch.ApptID)).Take(1)).ToList();

 

                this.grid.OnApplyTemplate();

 

                this.grid.SelectedItem = lstFind2.Take(1);

Hi Jon The Nerd,

If you try to set SelectedItem too early (before RadGridView is shown for the first time) the SelectedItem will not be changed. We will fix this problem as soon as possible. Currently you could workaround the problem by using the DataLoaded event:

private bool initialized = false;
  
private void clubsGrid_DataLoaded(object sender, System.EventArgs e)
{
    // DataLoaded will be called multiple times 
    //so we make sure that our logic will be executed only once
    if (initialized)
        return;
  
    initialized = true;
  
    List<inv_mstr> lstFind = this.grid.ItemsSource as List<inv_mstr>;
    List<inv_mstr> lstFind2 = (lstFind.Where(i => i.inv_no == Convert.ToInt32(sch.ApptID)).Take(1)).ToList();
  
    this.grid.SelectedItem = lstFind2.Take(1);
}

Also, it is not recommended to call OnApplyTemplate manually.

Sincerely yours,
