[Solved] TabStrip not always reflecting ActivateWindow() change

Hello,

I am tasked to replicate the New Tab functionality of Google Chrome. I have attached sample code below that mostly accomplishes this. However there is still one bug that I am unable to fix, and it is related to the RadDock tabstrip not redrawing after ActivateWindow() is called.

To reproduce this problem, please run the following code. You should see a tab named "New Tab 0" and a mini-tab to its right, which will create additional new tabs if you click on it. Click the mini-tab so you have two named tabs. Then, right-click on the right-most named tab ("New Tab 1", unless you created more) and select "Floating" to pop it out. Here is where the problem happens. We never want the MiniTab to have focus, so the method MiniTabGotFocus() will have been called, which activates the window to its left. However, the tabs are not redrawn to reflect this. BUT, if you click on Form1 parent dialog to give it focus (or close that popped out window), the tabs will immediately redraw correctly. So the window to the left was in fact Activated, but the tabs do not reflect this until Form1 has focus again.

Does this make sense? I have tried to Invalidate() the TabStrip but that does not force it to redraw. I can only cause it to redraw correctly by clicking on the Form1 parent dialog to give it focus. What I would like help on is how to force the TabStrip to redraw.

This is using Telerik v2011-8-31.

Thanks,

Michelle

[Solved] Hide default MDI menu

Hi,

I'm using a RadForm as an MDI container and loading child MDI forms into it. I load the child forms in a maximized state but seem to be unable to hide the default MDI menu in the parent form.

The MDI section of the RadForm documentation says:

"When a MDI child Form is maximized, it automatically hides its title bar and the parent form displays a default MDI menu. This menu contains controls can execute the basic window commands on the currently maximized MDI child:"

I would like the "default MDI menu" to be hidden. I will control the windowstate of the child forms myself.

I've tried setting the MinimizeBox and MaximizeBox to false (on the child forms) and also changing the FormBorderStyle, all to no avail.

Any help or advice would be greatly appreciated.

Please see the attached JPG for an illustration.

Many Thanks,

Joe

Unresponsive when deleting with IsSpellCheckingEnabled = true

Hi,

If I enable spellchecking via IsSpellCheckingEnabled =true, when I delete text from the RichTextBox by holding down backspace or the delete key, the RichTextBox seems to pause, and I can't see the characters deleted one by one, and therefore can't tell when to release the delete key.

RichTextBox (obsolete as of Q3 2014 SP1)

Radgridview not accessible

Hi,

I have a strange situation.
Sometimes when I add a RadGridView to a form in design mode, the RadGridView is not accesible in the code editor.
Steps to recreate problem:
    *    create new project in VS2010
    *    Add form/RadForm (doesn't matter which one, I had problem with both forms)
    *    Add RadGridView to the form via designer, drag and drop on the form.
    *    Go to code editor via F7
    *    Add a method to the form "Public sub test"
    *    Start typing "Radgridview" the code completion doesn't find anything called radgridview.   See attached file.

This does not happen all the time. Anybody had thesame problem?

Kind regards,

Guy
