Want loop over Syncfusion.Windows.Forms.Grid.Grouping and set e.style.backcolor for specific row.

Hi Ashok,

You can try the code like this in the QueryCellStyleInfo event of the GridGroupingControl, to color any specific record(row) in grid.

void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
    if(e.TableCellIdentity.DisplayElement.Kind == DisplayElementKind.Record)
    {
        Element el = e.TableCellIdentity.DisplayElement;
        Record rec = el.ParentRecord;
        int recordIndex = this.gridGroupingControl1.Table.Records.IndexOf( rec );
        if( recordIndex == 3 )
            e.Style.BackColor = Color.Pink;
    }
}

Let us know if you have any further queries.
Thanks for using Syncfusion Products.

In your click event, set a flag (or create a collection of row indexes) to indicate that you want to color certain rows. Then inside the QueryCellStyleInfo, check this flag (or check if the rowIndex is in your collection), and if so, then set the BackColor as shown above.

The reason you need to do it this way is that the GridGroupingControl does not store properties for each row. It does this for efficiency (so you can have many, many rows). So, you cannot just set such properties on a row. To affect a visual property on a row or individual cell, you need to do it on demand in a an event (like QueryCellStyleInfo).

Now if you really want to store something on a row by row basis (so you can set it and not have to provide it in an event), then you can create a custom engine which will allow you to create your own row objects which will allow you to add properties such as a row color that you could set. The ResizableRows sample that we ship does this to add a RowHeight property to each row. You could similarly add a Color property, but generally it is simpler to set such properties dynamically in an event like QueryCellStyleInfo.
