Hi,
We are using having parent child hierarchical Telerik Grid. The grid is containing large number of records(77506 items in 7751 pages).After 2-3 mins,after clicking the Export to Excel button, It's throwing Exception as "Exception of type 'System.OutOfMemoryException' was thrown."



Using the below code for Export to Excel button click event.

gviewAuditTrial.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;
            gviewAuditTrial.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML;
            gviewAuditTrial.ExportSettings.IgnorePaging = true;
            gviewAuditTrial.ExportSettings.OpenInNewWindow = true;
            gviewAuditTrial.ExportSettings.FileName = "CRF_Details";
            gviewAuditTrial.ExportSettings.ExportOnlyData = true;
            gviewAuditTrial.MasterTableView.ExportToExcel();

Please let me know the solution for this.

Thanks,
Prasad

Hi,

I suppose this issue arises when you export large amount of data. Check the following forum thread which discussed similar scenario.
