Disable MenuItem Shortcut


the application I am writing has a MainMenu and a DataGrid

Now I have to edit the text of each cell in this grid. So far so good.
All works fine in editmode but if I press a key which is also a
shortcut it doesn´t work and the menuitem-clickevent will be

KeyPreview of each parent form and each mdiparent is disabled.

For example: There is a shortcut in the menu which will be called by
pressing the delete key. If I am in editmode of a cell and I press
this key the shortcut should not be called but the text in this cell
should be edited.

So I tried to remove the shortcut like following code of my own
datagrid (inherits UltragGrid respectively DataGrid):

**** CODE ****
/// <summary>
/// Disable all shortcuts in all superior forms
/// </summary>
/// <param name="oShortcut ">The shortcut which has to be
public void DisableFrmShorc ut(Shortcut oShortcut)
//Find parent form
Control oControl = this.Parent;
while(!(oContro l is frmEnhanced))
oControl = oControl.Parent ;
while(oControl != null)
for(int i = 0; i <((frmEnhanced) oControl).Menu. MenuItems.Count ; i++)
//Find an remove all shortcut which is equal oShortcut
this.RemoveMenu Shortcuts(((frm Enhanced)oContr ol).Menu.MenuIt ems[i],oShortcut);
//Is there another superior form (maybe mdiparent)
oControl = oControl.Parent ;
while(!(oContro l is frmEnhanced) && oControl != null)
oControl = oControl.Parent ;
/// <summary>
/// Search every subordinate menuitem and disable the shortcut
/// </summary>
/// <param name="oItem"></param>
/// <param name="oShortcut ">The shortcut which has to be
private void RemoveMenuShort cuts(MenuItem oItem,Shortcut oShortcut)
for(int i = 0; i < oItem.MenuItems .Count;i++)
//recursive call of this method to find all menuitems
this.RemoveMenu Shortcuts(oItem .MenuItems[i],oShortcut);
if(oItem.Shortc ut == oShortcut)
//Remove Shortcut ans disable menuitem
oItem.Shortcut = Shortcut.None;
oItem.Enabled = false;
//Remember all disabled shortcuts
this._aDisabled Shortcuts.Add(o Shortcut);
**** CODE END ****

When I am entering the editmode of each cell I call the first methode
above to disable the shortcuts. This works fine and the menuitem(s)
are disabled and the shortcuts arent displayed in the menu but the
menuitem-clickevent will be performed again and agian.

Does anyone have an idea how I can resolve this problem??? I would be
very glad if someone can help me!

Best regards

Marcel Stallmach

hope you understand my english and what I mean ;)

I am writing a C# app that has a Menu. Some of the menu items will have short cuts that do not exist in the Shortcut enum. I would like the custom shortcuts to appear on the menu but as far as I can tell there is no way to add a short cut that is not in the Shortcut enum. I have my on keyboard hook so I am not worried about the custom shortcut magically working. I just want it to appear nicely formated on the menu. Anyone have any...

I'm trying to enable a menuitem in the parent form from a mdichild. Rather than making the menuitems public, I'd go for a public method in the parent form to do the change, but when I call the method from the mdichild, I get this error: C:\MyProjects\Visual Studio Projects\Tournament\Forms\frmLogin.cs(69): The name 'test' does not exist in the class or namespace 'Tournament.frmLogin' frmLogin is the mdichild.

Here's my newbie question: I have several VB forms which are all inherit a standard template form that I made.

Ideally, I suppose I'd like to constantly monitor the clipboard for data, (in a thread?) but I'm not even sure how I'd...
