RadDataGridView

Hi.
I'm new with this product and I have some problem with RadDataGridView
1. When I define more than 21 columns, I can not choose the columns 21 and more to set their property.
2. Some time (not always) I can not add more than one column to the Grid (when I open "Open Property Builder"). I have to click OK and open it to add another column.

[Solved] Loading multiple themes for similar controls

Hi,

Ive got a complex MDI application which Im trying to theme. Ive tried a few different ways to create multiple themes that the user can chose between and the only way I can get it to work is if I create a ControlDefault theme for most controls, and any controls that need to be different, like panels that need to show different colours I create a separate theme file and set the ThemeName property on the panels to match up the the correct theme. Then to swap between themes I have a different set of files with the same ThemeNames.

This works great, but I cant figure out how to unload a theme, also if I have 2 themes, light and dark and the form loads with the light theme, then I set it to dark, if I try to set it back to light it wont apply. How can I unload the theme, or properly switch between themes?

To load the themes Im using ThemeResolutionService.RegisterThemeFromStorage(...);

Also

Ive built a control which inherits from RadPanel, and when I try and theme it, the theme will not apply. I had a look at the resulting xml from the Visual Style Builder, and it was setting the ControlType attribute in the RadStylesheetRelation node to RadPanel instead of my class. I manually set this to my class and it worked fine. While this works, it is a pain, and if the client wants to create new themes later they will need to manually change the xml.

Any help would be appreciated

Thanks

Wrong entries in forms designer for localized vb app

Hello again,
I am using Visual Studio 2008 for a Visual Basic project together with RadControls for WinForms Q1 2009.
My app is localisable and I have two resource files called "UiSettings.en-GB.resx" and "UiSettings.resx".
When adding a rad control to my form, lets say a RadGroupBox (but the problem occurs also with a TabStrip) the following entries are added to the forms designer:
"Me.radgrb_ConnAcrobat.FooterImageKey = Global.COACH.UiSettings_en_GB."
"Me.radgrb_ConnAcrobat.HeaderImageKey = Global.COACH.UiSettings_en_GB."

including the points at the end, where COACH is the namespace of my app.
The error message is "UiSettings_en_GB is no member of COACH"

I can manually delete the entries but they appear again after compiling.
Can't work with all these error messages.
Could you please help?
Thanks in advance
Roberto Wenzel

Four Panes: How Might I Do This?

Just looking for suggestions on how I might implement the following:

I want a rectangular screen divided into four quadrants, each with resizable content. I should be able to drag the dividers between the panes to adjust the sizes, giving more real estate to whichever pane I want. I know I can do this with the docking manager, although it seems there's no way to put my cursor at the intersection of all four panes and adjust both horizontal and vertical sizes at the same time. (Correct me if I'm wrong.)

But, the other thing I'd like to do is to be able to maximize any single pane to take up the space of all four panes (covering the other three) with a button click (or right-click menu) and just as easily restore the pane back to where it was docked before so I can see all four panes again. This doesn't seem to be a possiblity with the docking manager.

Anyone have any suggestions on how I might do this with other controls?

RadGridView

We are evaluating the RadControls for Winforms. Using the RadGridView that is bound to a custom object, when trying to add a new row we receive the following message:
System.MissingMethodException: Constructor on type 'MyObject.whatever' not found. at System.RuntimeType.CreateInstanceImp(bind......etc..
Most likely something up with our object but would like your advice.

Secondly, is there an event that is available to tie into the Add New Row event?

Thirdly, is there an event for the Filter Event before the filter is applied or evaluated, so that we can add some custom logic?

Thanks for the support!

Multiple Series On Top Of Each Other

If I have two series, is it possible to show the second series on top of the first? Any help would be greatly appreciated. Basically what I am trying to do is show an overlap in time as a red bar and the rest of the bar as a different color.
