Help With Updating Designer Code to the New Version

[Eric]

Hi, I have just downloaded the newest version of radControls for WinForms, and it looks + works great!

However, the rightColumnItems are not compatible with Q1 2008 SP1, since I get an error in the designer code at

this

.radMenuItem4.RightColumnItems.AddRange(new Telerik.WinControls.RadItem[] {this.radMenuComboItem1, this.radMenuItem7});

'Telerik.WinControls.UI.RadMenuItem' does not contain a definition for 'RightColumnItems'

I also get a bunch of warnings: 

'Telerik.WinControls.UI.RadMenuItemBase.HasTwoColumnDropDown' is obsolete

When I select the form, I get a message saying:

Error parsing RadItem: Children collection doeas (typo: does) not match - index is not valid radMenuComboItem1 [Telerik.Wincontrols.UI.RadMenuComboItem](1).MenuComboItemBorder[BorderPromitive](1).

In Visual Studio 2005: when I select the menu at runtime I get an error:

Cannot remove the specified item because it was not found in the specified Collection.

How can I change this code to fit Q2 2008?

Thanks in advance.

Hello Eric,

Thank you for writing.

Sorry for inconvenience caused.
We have a breaking change on the RadMenu which includes removed RightMenuItems.

You should change the type of radMenuItem4 in Designer.Cs from RadDropDownButtonElement to RadApplicationMenuButtonElement
and change line
this.radMenuItem4.RightColumnItems.AddRange
that adds Button items to Right Menu to
RadApplicationMenuButtonElement.DropDown.RightColumnItems see sample code bellow:

this.radMenuItem4.RightColumnItems.AddRange(new Telerik.WinControls.RadItem[] {this.radMenuComboItem1, this.radMenuItem7});

should be

RadApplicationMenuDropDown dropDown = this.radMenuItem4.DropDownMenu as RadApplicationMenuDropDown;
dropDown.RightColumnItems.AddRange(new Telerik.WinControls.RadItem[] {this.radMenuComboItem1, this.radMenuItem7});

Hope this helps.

Thanks.

I changed RightColumnItems to Items and reboot the solution a few times.  Visual Studio seemed to fix the problem by itself.  The only thing that happened was that two extra elements were generated, which I deleted.

Will this affect my application?

Thanks again.

Hi Eric,

I don't expect any problems and if your menu looks fine and does not have missing items, then everything is OK.
