 How do i do the same scenario in XAMGrid and Silverlight

 I don't see a event as ultrawebgrid, i see only

xamGrid1_GroupByCollectionChanged(object sender ,GroupByCollectionChangedEventArgs e )

I need the same to expand all rows in the grouped columns i have 2 columns grouped.

I understand this is asp.net ultragrid forum, but infragistics team probably can keep this to the right person

Thanks

Hello Mahfuz,

The UltraWebGrid GroupByRowStyle property affects all the GroupByRows for the grid and cannot be set for a specific GroupByRow by Column Index or Key. 

To set different BackColors for GroupByRows, use the InitializeGroupByRow event.  The following code demonstrates how to check if the current Row in the InitializeGroupByRow has a ParentRow, if the grid were grouped by more than one column and if true, checks if grouped by two specific columns checking their Keys and if true, sets e.Row.Style.BackColor to SeaGreen else will set e.RowStyle.BackColor to Red:

void UltraWebGrid1_InitializeGroupByRow(object sender, Infragistics.WebUI.UltraWebGrid.RowEventArgs e)
{
    if (e.Row.HasParent)
    {
        if ((e.Row.Band.Columns[6].IsGroupByColumn) &&
                                                  (e.Row.Band.Columns[5].IsGroupByColumn))
        {
            e.Row.Style.BackColor = Color.SeaGreen;
        }
    }
    else
    {
        if ((e.Row.Band.Columns[6].IsGroupByColumn) || (e.Row.Band.Columns[5].IsGroupByColumn))
        {
            e.Row.Style.BackColor = Color.Red;
        }
    }
}

Please try the above code in your application and let me know if you have any questions.

Thank you.

Hello Sameh,

Thank you for posting your inquiry to the Infragistics ASP.Net Forums.  To expand all the GroupBy rows, handle the UltraWebGrid InitializeGroupByRow event and call the Expand method for the rows as shown here:

protected void UltraWebGrid1_InitializeGroupByRow(object sender, RowEventArgs e)
{
     e.Row.Expand(true);
}

Please let me know if this information helps or if you have any questions.
