Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
posted

Hi,

I am using "WebHierarchicalDataGrid" with List as a data source.  In data source there is Parent and Child relationship like Dept -> Employee.

I am exporting grid data using "WebDocumentExporter". Now when I export data using "DataExportMode = DataExportMode.AllDataInDataSource" then exporter throws following error.

"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"

If I remove "DataExportMode = DataExportMode.AllDataInDataSource" property setting of "WebDocumentExporter" it export first level of grid data successfully.

I am using Infragistics 2011.1 version. Please help me to resolve this issue.

Thanks.

    we have migrated our Infragistics from v5.3 to V11.1 . There were absolutely no compilation errors. Also all pages seem to work fine except one page. In that page we use the UltrawebGrid. When debugged, the grid seemed to bind succesfully in the Page_Load and also the Initialize event of the grid also went through successfully. But finally we are getting the below error. We are not able to figure out which code is throwing this exception. But the error message seem to be with the grid only. could you please suggest a solution for this issue. Fixing this outstanding solution would save all our migration effort. Please help.
