Error in paging in Group by ultra web grid
posted

Hi,

I am using the ultrawebgrid and using the Outlook group by for grouping the records.

I have n number of groups and each group can have n number of records.

In my grid i implemented the paging logic and I display only 10 records per page.

Also I use the following 2 lines for expanding the column while the page is loaded first time.

Grid.DataBind();

Grid.PerformGroupRows();

Grid.ExpandAll();

I am having the recordset which has the 2,3,4,5,6...etc page datas.

I have done that logic in this event LinkagesGrid_PageIndexChanged and when the above line is executed in perform group rows, my page breaks. I am pasting the error for your reference

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. Parameter name: index at System.Web.UI.ControlCollection.get_Item(Int32 index) at System.Web.UI.ControlCollection.RemoveAt(Int32 index) at Infragistics.WebUI.UltraWebGrid.RowsCollection.Sort() at Infragistics.WebUI.UltraWebGrid.UltraWebGrid.SortGroupRows(RowsCollection rows) at Infragistics.WebUI.UltraWebGrid.UltraWebGrid.PerformGroupRows() at UserControls_ViewLinkages.LoadData()
