Gruping

[Daniel]

Hello,

I dont know how to solve this:
 I have a RadGridView grouped by program code and I know that each group has always 2 rows. And I want in the GroupHeader to be displayed some data from not "group by" collumns from the second of the rows in that group. Is it possible?

Hi Daniel,

Thank you for contacting us.

Yes, this is possible by processing the GroupSummaryEvaluate event. Consider the code snippet below:

grid.MasterGridViewTemplate.GroupByExpressions.Add(new GridGroupByExpression("Value GroupBy Value"));
grid.GroupSumaryEvaluate += new GroupSummaryEvaluateEventHandler(grid_GroupSumaryEvaluate);

void grid_GroupSumaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e)
{
    if (e.Group.RowCount > 1)
    {
        e.FormatString = "Group value: " + e.Group[1].Cells["Value"].Value.ToString();
    }
    else
    {
        e.FormatString = "This group contains only one row!";
    }
}

I hope this helps. Should you have further questions, do not hesitate to ask.
