You can change the background color of RowHeader Cell by using QueryCellInfo event that is used to customize each and every cell in the required format and the event is raised for each cell that requires redrawing. This is illustrated in the following code example.
C#
void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
//You have to skip Header Row whose row index value is zero
if (e.Style.RowIndex > 0)
{
//The styles are applied for RowHeaderCell by checking the Column index is zero or not (RowHeaderCell column index is 0)
if (e.Style.ColumnIndex == 0)
{
//Render the record index from the value of the Rowindex
int recordindex = this.gridDataControl.Model.ResolveIndexToRecordPosition(e.Style.RowIndex);
//Here the record retrieved based on the record index position
var record = this.gridDataControl.Model.View.Records[recordindex];
//Apply color by checking whether the Business object Status equals true
if ((record.Data as Data).Status.Equals(true))
{
e.Style.Background = Brushes.Pink;
}
}
}
}
Execute the above code to change the RowHeader’s default color into pink color whose corresponding status cell value is true that is illustrated in the following screenshot.
