IndexOutOfRange Exception
posted

Hi I am facing this exception when I am going to assign data source to grid.

Please tell.

I am using ultradatasource and here is the code.

  foreach (ColumnInfo colinfo in ColumnCollections)
                    {
                        this.ultraDataSource.Band.Columns.Add(colinfo.GetColumnKey(), Type.GetType("System.String"));
                    }

 this.ultraDataSource.Rows.SetCount(GetRowCount());
                    this.resultsGrid.DisplayLayout.LoadStyle = LoadStyle.LoadOnDemand;
                    this.resultsGrid.DataSource = this.ultraDataSource;    at this line below exceptionoccurs.

 This happens when I am laoding file above 1000000

This is exception text.

    Hi Syed,

    There's not much here to go on. 

    What version of the grid are you using? Do you have the latest Hot Fix? I remember some problems with the SparseArray that were fixed a long time ago, so maybe you are using an old version. 

    Another reason for an error like this is if your application is using multiple threads and you are trying to bind across the threads.
