CharAggregate

[Hu Anderson]

I am trying to use the CharAggregate summary type to show a description in a summary column.

I can not get this to display anything other than a null character, if I use Maximum etc. If I put actual text, "Test Desc" in for the format then that will display for all summaries.

Any ideas?

Hi Hu Anderson,

Here is a code snippet that demonstrates the technique to set the user defined value in the summary column of the GroupCaptionSummaryCell.

///Code>>>>>>
this.gridGroupingControl1.QueryCellStyleInfo += new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo);
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
if (e.TableCellIdentity.TableCellType == GridTableCellType.GroupCaptionSummaryCell)
{
if (e.TableCellIdentity.SummaryColumn != null && e.TableCellIdentity.SummaryColumn.Name.Equals("Sum"))
{
GridCaptionRow gcr = e.TableCellIdentity.DisplayElement as GridCaptionRow;
GridCaptionSection gcs = gcr.ParentSection as GridCaptionSection;

Group grp = gcs.ParentGroup;
if (grp.IsTopLevelGroup)
return;

string value = grp.Category.ToString();
e.Style.Text = "Test desc" + e.TableCellIdentity.RowIndex; //value.ToString();
}
}
}
///Code>>>>>>

Best regards,
