Hello!

I have a really strange behavior with my project. If I put a RadImageButton to the ToolStripItem and I assign an image with red in it, it is not showing it. In design mode everything works fine, but as soon as I start the program (even from VS), I got an empty space for the image.

I tried with several pictures (mainly with cancel and stop and so on), but as soon as the red appears, my image disappear. Other images works fine. The images are all pngs with transparent background.

I attached two screenshots and you can download a simple project from http://www.wellensteyn.ro/temp/HQ.ZIP

Does anybody experienced something like this? What can be the problem?

Thanks: Botond

GridViewComboBoxColumn: let user add values that are not in datasource

Hi,

I have a GridView with a GridViewComboBoxColumn that has a list of strings as the datasource and is bound to a string property in my ViewModel. Is it possible to let the user add new values to the string-list by typing in the GridViewComboBoxColumn editor and not reject those values when they are not already in the list?

At the moment, when I type a string that is not already in the bound list, the string is saved in the editor (when I enter the cell again after leaving it, the value is still there) but not propagated through the ValueChanging event and also not written to the underlying ViewModel.

I'm looking for a way to either

Add the new value directly to the string-list and to the ViewModel's property
Get notified about the change with the new, not-in-list value and be able to put it in the string-list manually

Is there a way to do this?

Thanks in advance.

Hiding dropdown arrow

Hi,
Is there any way to hide the dropdown arrow in order to create an autocomplete textbox? I know you can do it in your ASP controls but I can't find an equivalent way to do it in the winforms controls. Thanks

Imprope Column Alignments on Conditional Format Rows

On Rows that have ConditionalFormattingObject's on one or more Columns, it's ignoring at least the MiddleRight (if not all) value of the TextAlignment Property and left-aligning at least the numeric (if not all types of) Columns. I verified that the TextAlignment Property is set to MiddleRight before and after adding ConditionalFormattingObject's and before and after calling the Show method on the Form.

Custom Cell Editor

Hello,
I have a grid with a GridViewDecimalColumn. When this cell goes into edit mode, I would like to have the regular editor displayed but along side it I want to have a button that the user can click to launch a modal dialog. I have searched extensively on the forums and I have not found a way to accomplish this with the Decimal column (there appear to be other samples using a gridviewcomboboxcolumn, but I could not adapt that to meet my needs). FYI - I am using the 2009 Q2 SP1 release.

Any help is greatly appreciated.

Thanks,
Sean

Can't Get VTB Theme to Work

I like the new Visual Style Builder, and also watched a quick How-to Video on it, but I can't seem to get the custom theme to work. I created a Theme for RadMenu on the Theme Builder. Save it, and exported the zip file. I've copied the Zip Content (CSS and folder Menu) into the "App_Theme\Default" folder. I then set the RadMenu's EnableEmbeddedSkins="false", and set Skin to the new skin name. Nothing happens. Please help.

I am running IIS 7 on Vista 64.
