ShowParentGroupSummaries don't update

[Nadia Sangiovanni]

Dear Support,

We use RadGridView with Summaries rows and Parent Summaries rows. On loading all sum are correct. But when the user change a value in the grid, the summaries are updated but not the parent summaries rows.

I attached pictures showing the problem. AfterLoad is the gris after the form is loaded, and afterChange is the gris when I change the value of the first row from 75 to 65. Top Summaries and group summaries have updated but not the parent summaries.

Please advise,
Nadia

Hello Nadia,

Thank you for bringing this issue to our attention.

I confirm that the issue appears in our latest release and I logged it in our issue tracking system and you can track its status by following this link. The issue will be addressed in one of our upcoming releases. I updated also your Telerik points.

You can work around it by handling the CellValueChanged event. Consider the following code snippet:

void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{
    if (e.Column.Name == "Value")
    {
        GridViewGroupRowInfo parentRow = e.Row.Parent as GridViewGroupRowInfo;
        while (parentRow != null)
        {
            if (parentRow.TopSummaryRows.Count > 0)
            {
                GridViewSummaryRowInfo summaryRow = parentRow.TopSummaryRows[0];
                MethodInfo mi = summaryRow.GetType().GetMethod("ClearCache", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic);
                mi.Invoke(summaryRow, new object[] { });
                summaryRow.InvalidateRow();
            }
            parentRow = parentRow.Parent as GridViewGroupRowInfo;
        }
    }
}

I hope this helps.
