DataGroup Rows replacement

[Sara]

In the GroupSummaryEvaluate event, I want to loop through the data rows in the group looking for a row based on some criteria against the data in that row.  I then want to display some data from this row in the group description.  I can do this using e.Group.Rows.  However, the Rows property is marked as deprecated and the Items property is not accessible.  What is the best way to do this?

Hello Sara,

You should access the GroupRow property and iterate its ChildRows collection. Here is a sample:

void radGridView1_GroupSummaryEvaluate(object sender, GroupSummaryEvaluationEventArgs e)
{
    int sum = 0;
    foreach (GridViewRowInfo row in e.Group.GroupRow.ChildRows)
    {
        sum += (int)row.Cells["Value"].Value;
    }
    e.FormatString = "Sum: " + sum.ToString();
}

Do not hesitate to contact us, if you have further questions.
 
Kind regards,
