I have a RadGridView with a RadDataPager, I put the page size to 0 and then tried to export, the exporting works fine, but when try to set the page size to its original value, the RadGridView doesn't show any elements. However the ItemsCollection has all the elements, and they only appear on the RadGridView when page changing occurs. 

I'm basing my code from the GridView Exporting Paged Data example of your web site Demo.

Please Advise  

Here is an example of my code:

string extension = ((TextBlock)(((System.Windows.Controls.ListBox)btnExport.DropDownContent).SelectedItem)).Text.ToString();

 

            ExportFormat format = ExportFormat.Html;

 

            switch (extension.ToUpper())

            {

                case "HTML":

                    format = ExportFormat.Html;

                    break;

                case "XLS":

                    format = ExportFormat.ExcelML;

                    break;

                case "TXT":

                    format = ExportFormat.Text;

                    break;

                case "CSV":

                    format = ExportFormat.Csv;

                    break;

            }

           

            dialog.DefaultExt = extension;

            dialog.Filter = String.Format("(*.{0})|*.{0}|All files (*.*)|*.*", extension);

            dialog.FilterIndex = 1;

 

            if (dialog.ShowDialog() == true)

            {

                originalPageSize = radDataPager.PageSize;

                originalPageIndex = radDataPager.PageIndex;

                using (Stream stream = dialog.OpenFile())

                {

                    radDataPager.PageSize = 0;

                    GridViewExportOptions exportOptions = new GridViewExportOptions();

                    exportOptions.Format = format;

                    exportOptions.ShowColumnFooters = true;

                    exportOptions.ShowColumnHeaders = true;

                    exportOptions.ShowGroupFooters = true;

                    exportOptions.Items = (IEnumerable)radDataPager.PagedSource;

                    radGrid.Export(stream, exportOptions);

                }

                radDataPager.PageSize = originalPageSize;

                radDataPager.PageIndex = originalPageIndex;

                radGrid.Rebind();

            }

I have prepared a test project with our latest binaries, utilizing the code you have provided and have never faced such an issue. I am sending it for you reference. Please, have a look at it and inform me whether there are any differences between my approach and yours.
