Hello,

In the QueryCellStyleInfo event for a particular cell in a summary row (not sure if its called a summary row, I''m talking about the row that gets created when you drag a column heading into the groupDropArea), how do I access a data value in another cell in that summary row.

So if we have 2 columns (X and Y), and I''m in X''s QueryCellStyleInfo event for the summary row cell, how do I access the data value in Y''s summary row cell?

Thanks for all the help over the past few months!

Eric

Hi Eric,

You can use the GetSummaries method to get the summary value at the specified index. Below is a code snippet.

switch (e.TableCellIdentity.TableCellType)
{
case GridTableCellType.SummaryFieldCell:
{
GridTable table = e.TableCellIdentity.Table;
GridSummaryRow row = e.TableCellIdentity.DisplayElement as GridSummaryRow;
GridSummaryRowDescriptor summaryRowDescriptor = row.SummaryRowDescriptor;
GridSummaryColumnDescriptor sumCol1 = summaryRowDescriptor.SummaryColumns["ColumnName"]; // name of summary column here ...
if (sumCol1 != null )
{
SummaryDescriptor sd1 = sumCol1.SummaryDescriptor;
if (sd1 != null)
{
int indexOfSd1 = table.TableDescriptor.Summaries.IndexOf(sd1);
CountSummary summary1 = (CountSummary) row.ParentGroup.GetSummaries(table)[indexOfSd1];
Console.WriteLine( "Summary value :" + summary1.Count + ":::" );
}
}
break;
}
}

Thanks for using Syncfusion Products.

Best Regards,
Haneef

I have a GroupCaptionSummaryCell, therefore your line of code...

GridSummaryRow row = e.TableCellIdentity.DisplayElement as GridSummaryRow;

threw an error.

Thanks,

eric
