Hi everyone,

I would like to add a shortcut to my RadButtonItem without any Keys modifiers.
And the problem is I have no idea how I could make it without displaying the Delimiter - "+" (RadShortcut.Delimiter).

Code:


Result:
Menu item look:
"text        +F5"

Any ideas how I could remove this Delimiter?

Thanks in advance,
Adam

I am trying to inherit RadMenuItem (sample bellow), in order to add more properties required by our application.


When I try to add this new RadMenuItem in a RadMenu object, the visual display of the item is different from the actual RadMenuItem. I guess it is a ThemeEngine glitch. Do you have any advice on how to correctly inherit RadMenuItem?

This is a sample form where two menu items are added, one standard RadMenuItem (test1) and one from the inherited TestMenuItem (test2). Form1 has a RadMenu control added and it is a standard Windows.Form form.

In the attached image you can see the resulting runtime form with the difference in visual display of the two menu items.

We are currently evaluating your WinForms controls and we have little to no experience with your libraries :).

Ok. I'm not 100% sure how to explain this: so here goes.

Hi
i'm using radGridView and it seems that i cant set the grid header font at design time.
i've tried Element Hierarchy Editor and i've set my font in GridHeaderElement, but it seems it does not work.

i'm using 2010 Q2 and my grid is in ( RightToLeft = True) mode.

is there any other way to modify grid header at runtime?

ps: i also cant set header height in Element Hierarchy Editor  :(

tanx in advance

here is the idea of the code used to demo this bug.

create a new class


public partial class MainForm : Applications.UI.ShadowForm
{
   //in here create another class
   ChildClass cClass = new ChildClass()
 
   //link the parent object to the child class
   cClass._parent = this.

   //in the InitializeComponent tell it to hide the max button
   ....
    this.MaximizeBox = false;
   ....

  //tell the application to show you child class
   cClass.Show()


}


in the  cClass modifiy the parent MaximizeBox  to true

Result the box does not display untill you resize the parent. forcing it to re-draw.

Hi,

I am using "Edit UI elements" to style a RadGrid.
As soon as i change anything to do with Header part it breaks my application.

Kind Regards,

Hi,

I want to add a button or linklabel in radMultiColumnComboBox at specified column of specified row. Basicaly i want to achieve the following functionalities (PFA also):

•  Replace the second col of fourth row in this dropdown "(Choose)" with a control and open a date selector control on that control's click.
• Remove only horizontal lines of radMultiColumnComboBox2.EditorControl.
• Remove space between the EditorControl's (grid inside multicolumn combo) border and combo's border. 

 

I am using telerik controls for windows application.


Thanks in advance,
