clearing summary descriptors

[Catinat Velmourougan]

hi

I have an application where the user selects cols that have to displayed on the grid. Each time the user selects I clear all the existing lists and create new ones. I clear the following lists :

tableDescriptor.Columns.Clear();// don''yt clear these we''ll need them
tableDescriptor.VisibleColumns.Clear();
tableDescriptor.GroupedColumns.Clear();
tableDescriptor.SummaryRows.Clear();
tableDescriptor.SortedColumns.Clear();
tableDescriptor.ExpressionFields.Clear();
tableDescriptor.ResetSummaries();

Even after doing this some columns are remaining in a list probably a summarydescriptorcollection,
so say i have col1, col2, col3, col4, col5 and then i choose col1 and col2 then the following error comes up

SummaryDescriptor col3AutoSizeMaxLength: Field col3 not found.
SummaryDescriptor col4AutoSizeMaxLength: Field col4 not found.
SummaryDescriptor col5AutoSizeMaxLength: Field col5 not found.

How to clear SummaryDescriptorCollection?I cant even find this property.I am using a grid grouping control.

You might try adding this code to se if it helps.

foreach(GridSummaryRowDescriptor rd in this.gridGroupingControl1.TableDescriptor.SummaryRows)
	rd.SummaryColumns.Clear();
