Error Clicking on Filter Row of Date Column in 2009Q3Beta

I just installed Telerik Q3 2009 WinForms BETA (2009.2.9.1016) over Q2 2009 (2009.2.9.729) and clicking on the Filter Row of a Date Column started generating an error.

Add chart or any other control to a cell

What I wantto do is in the CellFormatting event(of elsewhere) I want to dynamically add a chart to a cell.
I can create the chart from code with no problem but I don't see a way to add a chart or any other control to a cell.
What I thought I would be able to do is this(pseudo):

GridCellElement cell = e.CellElement;

cell.Controls.Add(createChart(series1Val, series2Val));

Is there a way to add a chart to a grid and or a cell specifically?
Of if I need to do it at the column level(and use values from other columns) or any other level, please let me know..

Thanks

--Chuck

OnActivated is not getting called in Tabbed documents

Hi,
I am using a RadDock control with AutoDetectMDIChildren set to true. I have been given forms to be hosted as tabbed documents. I do this by setting the forms' MdiParent property to the main form and then calling their Show methods. These forms override the Form.OnActivated method. This method is never called.

Here is a simplified example:

    
                public partial class MdiChild : Form  
        
                {  
        
                    public MdiChild()  
        
                    {  
        
                        InitializeComponent();  
        
                    }  
        
                    int counter = 0;  
        
                    protected override void OnActivated(EventArgs e)  
        
                    {  
        
                        label1.Text = string.Format("Activated {0}", ++counter);  
        
                    }  
        
                }

When I first show the form I would expect its Label1 to display Activated 1. If I click on another tab then back on this form's tab I would expect to see Activated 2 etc.

Thanks

Docking and serialization problem

Good morning.

I have problems with radDock layout and serialization. My problems are also visible in the application examples provided with radControls. I use Visual Studio 2008 Express Edition on a Windows XP OS. RadControls version is RadControls for WinForms Q2 2009 SP1.

In the test application Examples\Docking\Serialization, when I want to move ToolWindow1 on the left, I see in the preview that it’ll fill half the space of ToolWindow3. When I dropped ToolWindow1, the result is not the same, and the windows will not appear as in the preview.
When I modify the layout and then save the new layout, when I load the layout a new floating radForm will appear. Trying to move it around by clicking on the title bar causes it to disappear. Then, every time I try to load the layout again, all is ok. I mean: if I modify the layout and save the changes, the first time I reload the new layout I got the problem. If I save the layout again (with no changes), no problems arise.

The same behaviour I obtain in my applications.

Thank you.

[Solved] ListBox Selection Display is not refreshed after scrolling

Hi,
My ListBox is populated with more items than fit into it, and I can thus scroll up and down.
Now, when I select an item and then scroll until it is not displayed anymore, and then scroll back, the selected item is not shown in "selected" style anymore.
Only when I move the mouse over the item, it is displayed in "selected" style again afterwards.

This problem seems to be related with this one:
http://www.telerik.com/community/forums/winforms/gridview/radgridview-row-formatting.aspx

i.e. "Only the rows that are visible on screen have visual elements. When the grid is scrolled, the visual elements are reused for other logical elements."

But I want my ListBox to show the selected items. The user doesn't want to play hide and seek.
What do I need to do?

[Solved] No such property registered - winforms

I have RadControls for WindowsForms 8.1.0.0 installed on my Vista x64 machine. I recently upgraded RadControls for ASP.Net from Q1 2008 to Q2 2009. After the upgrade, with a little work, I got my ASP.net projects working wonderfully and was fired up. However, I went in to do a little work on a win forms project, and I started getting a "No such property registered" error when opening the designer. Looking through the forums, I found that other users experienced this when upgrading their win forms controls. It seems that my case is slightly different in that the conflict is occuring on Telerik.VSX.Controls in my GAC, which was put there by the ASP.Net controls. I can't uninstall it from the GAC becuase the installer has it protected. If I do a full uninstall of the ASP.net controls, the winforms projects work fine. Any ideas?

Thanks,
Alex Johnson
