Dear Xceed WPF datagrid experts, 

I am struggling with the WPF datagrid cell background changes. I used the following code but in result it shows something else,

If I select one cell to change the BG, say rowIndex=2, colIndex=3, and the in the spread in the same column (colIndex:3) multiple randomly row got marked. where I wanted only selected.

please update me if write any wrong code.

System.Collections.Generic.IList<SelectionCellRange> selItems = dataSpreadView.OrdersGrid.SelectedCellRanges;

foreach (var selectionCellRange in selItems)

{

int colIndex = selectionCellRange.ColumnRange.StartIndex;

int rowIndex = selectionCellRange.ItemRange.StartIndex;

DataRow dr = dataSpreadView.OrdersGrid.GetContainerFromIndex(rowIndex) as DataRow;

dr.Cells[colIndex].Background = System.Windows.Media.Brushes.Red;

}

Hi Parth,

The problem is that you are setting the background color directly on a specific DataCell. However, we use cell recycling, meaning cells that are moved out of view while scrolling or re-used to display the new ones. This is used to improve memory usage (instead of creating fresh new cells every time).

Instead you should do something like use a Style on DataCell that uses Triggers to change the Background color of the correct DataCells only.
