UltraCalcManager Error
posted

Hi,

I am adding UltraGrid grouping's through code using ...SortedColumns.Add(...) API and my requirement is to Limit the number of Grouped by rows (say to Top 10). Now when i mark all other rows in the Grid except the Top 10 rows as Hidden then i receive an exception. Is this the BUG in WinCalcManager? Can i resolve this issue somehow?

Can someone please help me on this.

 

Code Snippet:-

 private void grid_InitializeGroupByRow(object sender, InitializeGroupByRowEventArgs

e)

{

 

 

int i = 0;

 

 

if(e.Row.IsGroupByRow)

{

e.Row.ExpandAll();

MyApp.GUIDecorator.UI.Controls.

SortDefinition ?sortedColumn = GetSortedData(e.Row.Column.Header.Column.Key);

 

 

if (sortedColumn != null)

{

 

 

if(e.Row.Index >= sortedColumn.GetValueOrDefault().topncount)

{

e.Row.Hidden =

true;

}

}
