Questions on UI for WinForms Forum

We've been developing on TelerikWinForms 2008 Q2 since it was released.   This afternoon I installed 2008 Q2 SP1 to try out...

Why is it that the ValueChangingEventArgs NewValue/OldValue properties are now returning the display value of the dropdown and not the actual value?   This worked fine in the prior version.

For example my dropdrop code values are "1" and "2".   The display values are "Male" and "Female".   In the prior version I was getting the correct NewValue/OldValue of "1" or "2". Now I am getting "Male" or "Female".

Thanks

Is there a way to enable RadRibbonBar to show a transparent title header and show defautl Vista window header buttons for minimize, maximize and close? I've tried setting the ThemeName of the RibbonBar to ControlDefault but it still shows a window different from the ones in Office applications.

Thanks in advance and best regards

RadListBox/RadDropDownMenu

I would like to assign a RadDropDownMenu to a RadListBox. I can't seem to find a way to do this. RadListBox has a "ContextMenu" and "ContextMenuStrip" property but these refer to Winforms versions of a ContextMenu so I can't assign a RadDropDownMenu. I don't see any other properties on the RadListBox like say RadContextMenu like there is on the RadTreeView.

Am I correct that this functionality is missing? If it is there, how do I go about doing this?

How do SaveLayout() and LoadLayout() work?

Maybe I'm crazy, or maybe I'm blind, but I can't seem to find a good example on how to get the LoadLayout to work.

I have a grid, and I save the layout to a file, using SaveLayout(fileName), but then when I go to load it, the method throws the exception:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

I figured that I was just doing it incorrectly, but when I went to look for an example of some sort, I couldn't find one.
Can someone please help me out with this.

Thanks
Davey

Office 2007 Themes Quirk

I have used the RadTitleBar with the Office 2007 theme and dragging a window works fine. If I select Office 2007 Blue / Black / Silver on a RadForm I am unable to drag the window by clicking on the left side of the titlebar. In other words I have to click where the Form Caption is or anywhere to the right of it.

Is this a bug with the RadForm or an issue with the theme itself?

Property Builder in Vista 64 under Visual Basic environment crashes

Hi Friends,

I am trying to utilize the Property Builder functionality in VS 2008 running under windows Vista 64. Specifically I am using the Visual Basic environment in Visual Studio, and when I am trying to parametrize properties for the RadGridView Control usin Property Builder nothing happens. Property Builder opens up fine, I make all the necessary changes I want, but when I press OK the program closes and no changes are transfered to the control in the form. Any ideas?

Regards,

George

Rad Timeline

I'm not sure what sort of commerciability it would have, but a timeline control (a-la) http://www.dipity.com/user/tatercakes/timeline/Internet_Memes would be pretty cool. Perhaps it is something that could fit in Rad Scheduler, or in Rad chart as well.

Programmatically Selecting the Highlighted Item

Hi Guys,

How do I programmatically select the highlighted item?

We have implemented buttons on our grid. Please refer to http://www.telerik.com/community/forums/winforms/gridview/radmenuitem-in-radgridview-events.aspx for the code.

Currently the user must select the row before they can click the button. We have added code to the mouseover the change the radgrid icon and button color.

    
             void lblLabel_MouseEnter(object sender, EventArgs e)  
        
                    {  
        
                        this.gvManageDocs.Cursor = Cursors.Hand;  
        
                        ((RadLabelElement)sender).ForeColor = Color.Red;  
        
                    }

What I would like to do is when the user hovers over a button to auto select the row so they only have to click once to activate the button.

How do I do that?

NullReferenceException on RightClick event.

Hi,

we integrated GridView into a application and added a standard ContextMenu. When clicking on items in the GridView everything seems perfectly fine, but a click onto free space in the GridView results in an Exception:

                    Object reference not set to an instance of an object.         
                     
            System.NullReferenceException: Object reference not set to an instance of an object

            Telerik.WinControls.UI.BaseGridBehavior.OnMOuseDown(MouseEventArgs e)

            System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clickt)

            at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)         
            at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)         
            at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)         

We also discovered what seems to be a major problem to the GridView Designer. If you add a System.Windows.Forms.ContextMenu to the GridView using the Designer, save this state and try to re-open the Designer Visual Studio suddenly crashes..

Best wishes,
