GridViewBooleanColumn: strange behaviour when work with keyboard

WinForms RadControls Q3 2007
Visual Studio 2005
.NET 2.0

In other grid when I work with check box column I can set value of checkbox pressing space bar. I tried to set value with space bar but RadGridView have a strange behaviour.

1. on first load on first row press once space bar but grid doesn't check
2. after few seconds press another time space bar and grid check cell
3. go to second row with arrow keys
4. press space bar first time on second row and... check on first row disappear ?!? and on check on second row stay off
5. press space bar second time on second row and appears check on second row
6. go to third row and appers check also on the first row ?!?!?

I want a simple way to set checkbox in column similar Microsoft standard control ListView when set with CheckBoxes = true.

Placed a listview and a radgridview this code can reproduce error and my favourite behaviour.

Thanks in advance,
Emanuele Savarese

Export To PDF locks UI Thread

I am exporting a GridView of about 1500 rows and 20 columns to Excel and PDF. I do both in a BackgroundWorker Thread. The Excel export works fantastic and does not lock my UI. However, the PDF export takes significantly longer and locks my UI thread even though I am running it from a different thread.

What gives?

This is in my DoWork() method. It 'hangs' on the "RunExport()" line.

ExportToPDF pdfExporter = new ExportToPDF(uxResultsView);

pdfExporter.FileExtension = "pdf";

pdfExporter.PageTitle = "Provider Search Results";

pdfExporter.FitToPageWidth = true;

pdfExporter.ExportVisualSettings = true;

pdfExporter.RunExport(fileName);

How we can have the colum summation during running

Hi every body;
Dear all;

We would like to have the summation of each column row by row without using summary row item (the summary row item is used when we have grouping).
It is appreciated if you can answer that, how we can improve the calculation speed whilst the data source is very large (i.e. grater than 200,000 row).

the scheme of our propose is illustrated in following:

Column A     Column B               Calculated Column
   A                     10                       10
   B                      3                        13
   C    9    22
   D                      5                        27

Yours Sincerely.
