Is ChildrenOfType<GridViewRow> Broken?

[Randy]

I am using the latest internal build and even though the following comes back with 2:

int gridRowCount = _rgvwBreakpoints.Items.ItemCount;

This only comes back with the new row:

var rows1 = _rgvwBreakpoints.ChildrenOfType<GridViewRow>();

And this comes back with the header row, the new row, and the footer row:

var rows = _rgvwBreakpoints.ChildrenOfType<GridViewRowItem>();

This always comes back with null:

GridViewRowItem gridViewRow1 = _rgvwBreakpoints.ItemContainerGenerator.ContainerFromIndex(0) as GridViewRowItem;

Even though this loops through twice, I get null values as well:

foreach (var item in _rgvwBreakpoints.Items)
{
   var currentRow = this._rgvwBreakpoints.ItemContainerGenerator.ContainerFromItem(item);
}

It doesn't seem to matter what I have Virtualization (Row and Column) set to.

Hi Randy,

I have just tested it with 2011.1.526 binaries and it works as expected (the test project is attached for your reference). Are you sure that your RadGridView has already loaded the data properly at the time you are invoking ChildrenOfType<GridViewRow>() ?

Kind regards,

It seemed to work when I changed the code as follows:

 

 

 

 

GridViewRow row = (GridViewRow)grid.ItemContainerGenerator.ContainerFromItem(item);

 

 

 

 

if (row == null)

 

 

{

 

 

 

 

 

 

grid.UpdateLayout();

 

 

grid.ScrollIntoView(item);

 

row = (

 

GridViewRow)grid.ItemContainerGenerator.ContainerFromItem(item);

 

 

}
