Hi,

I would like to change the background of a cell at anytime.
For example, when a user click on a button, it colors a cell on a loaded grid.
I know the coordonates of the cell.

I tried to get throw the "ItemContainerGenerator" but I can't get all displayed cells.

How can I achieve that ?

Thanks,

Jeff

Hi JF Carré,

By default RadGridView used virtualization to boost performance and is some situations, like yours, this could pose a problem since just a small amount of UI elements will be created. By turning off the  selection mechanism you should be able to get any UI element on the grid:

    this.playersGrid.EnableColumnVirtualization = false;
    this.playersGrid.EnableRowVirtualization = false;
}
  
public GridViewCell GetCell(int rowIndex, int columnIndex)
{
    var row = this.playersGrid.ItemContainerGenerator.ContainerFromIndex(rowIndex) as GridViewRow;
    var cell = row.Cells[columnIndex] as GridViewCell;
  
    return cell;
}


Sincerely yours,
