get gridviewrow from radgridvview

[Dudy]

hi
i need to get spacific row in radgridview
 i tried this:
 foreach (var row in this.gridview1.ChildrenOfType<GridViewRow>())
                {                   
                    i++;
                    if (i == 200)
                    {
                        row.IsSelected = true;
                        territorymanagementactionitems.BringIndexIntoView(200);
                    }
                }

but after ~16 rows the debugger goes out from loop (i have more than 200 rows)

Hello,

It is not a good idea to work with physical containers such as GridViewRow. When there is row virtualization, you would have only 10-20 rows (depending on the grid height) which are recycled and reused for different data items as the user scrolls up and down. So you don't have rows for every single data item. You only have rows for the visible items.

You should always try to work with data items and Bindings, instead of relying on physical containers such as the rows.

if so , can you give me simple example how can i set focus on a spacific item ?(or row)

Hi,

If that item is not in the view, you cannot set focus on it like that. You can use the ScrollIntoView method of RadGridView and then programmatically select the item. More about this you can learn here.

If you want to use your original approach with ChildrenOfType, you will have to turn off row virtualization so that all rows are created, i.e. not only 16 of them.
