PanelBar - Outlook 2007

Hi Telerik,

I need a PanelBar similar to the Outlook2007.

I add in the container another RadPanelBar (Groupstyle: ExplorerBarStyle).

The problem is that I cannot modify the size of the container (size:50,50), I have tried with several options but it does not work.

Thank you

redraw issue with horizontal scroll

Working with RadGridView 4.0.2.0. I'm seeing some repaint issues when I bind the grid and both scroll bars are present. I've attached some screenshots. Basically I bind the grid with a very tall/wide table so that both scrolls are on. Then I move the hscroll back and forth a lot. The grid gets totally messed up. I guess I can't attach pics?

Dynamic AutoComplete on text editing

We want to provide our users with AutoCompletetion in a ComboBox. The problem is that the data source is containing alot of items, so we need to limit the suggestions based on what the user is writing.

So if the user enters Ab, we do a search in our database for entries starting with Ab and want to display those in the AutoComplete suggestor.

Here is our initial try to solve this:

private void radComboBox1_TextChanged(object sender, EventArgs e)
{
    radComboBox1.Items.Clear();

    foreach (string s in Accounts.Current.FindPartial(radComboBox1.Text))
        radComboBox1.Items.Add(new RadComboBoxItem(s));
}

This seems to work ok as long as you keep typing, but once you start using arrow keys to select an item in the dropdown, we get an exception:

Index was out of range. Must be non-negative and less than the size of the collection.
(This happens in Telerik code inside radComboBox1.Items.Clear())

We then tried to use the KeyPress event instead, but this didn't help us, as the ComboBox text property isn't updated at this point, so we cannot do a proper search string.

Any idea how we can solve this problem?

Ribbonbar Background Color

I change the ribbonbar's background color to black in Visual Studio Express (VB). It does change in the IDE, but when I run my app, the ribbonbar appears blue, not black.

I am using ribbonbar 2006 Q4, VB Express 2008, Vista Ultimate, no aero effects.

Thanks

Issues with CAB enabling Kit

Let me first say that I an fairly new to CAB and SCSF. I have downloaded the CAB Enabling kit from telerik and I must say it is not very easy to implement. Here are my issues (if anyone can point me in the right direction or help out I would greatly appreciate it):
1) The documentation on how to implement the Telerik components within the toolkit are lacking.
2) I'm running into a lot of issues when trying to alter the Shell form to use all telerik controls (including the form itself to be a Telerik ShapedForm.
The primary issue I am having is exposing the Telerik RadMenu as the MainMenuStrip. The property on the ShapedForm for MainMenuStrip will not accept a RadMenu. This is then causing issues when it attempts to Register the site extensions. The only work around I could come up with was to expose the RadMenu as someting other than a private member to the form (making it a public member basically).

The example application that came with CAB enabling kit didn't seem to have this issue because it seperated the shell as a CAB view.

Am I missing something here? I am very new to the Telerik controls, so maybe i'm just missing something.

Thanks!

How to set a Tooltip on a RadPanelbarGroupElement?

Hi,

I have an app where some UI-Element Text strings must be set from a DB.
The first approach was to iterate through the forms controls and set "Text" or "Caption" on the elemnts depending on their Name (ID).

This should also be done for Tooltips.

First problem - RadPanelGroupElement is not a control.
I could solve this via setting the controls public and working with reflection.

But the next problem is - how to set a ToolTip to RadPanelGroupElement?
Since RadPanelGroupElement is no control tooltip1.SetToolTip(RadPanelGroupElement1,"my Text") does not work.

I can set the tooltip for the PanelBar - but this shows ONE tooltip on every panel (always the same).
What I was looking for - each panel it's own tooltip.
Next I found a property on the RadPanelGroupElement called ToolTipText.

Looked like what I what I was searching for.
But whatever value I set - nothing happens.

If I set the ToolTip for the PanelBar - I always get this one.
--regardless what I enter in ToolTipText for the panels.
If I do NOT set TT for the PanelBar - I get no ToolTip at all.

My Questions:
-What is the use of ToolTipText on the RadPanelGroupElement element?
-How can I build a panelbar where every Panel has it's own Tooltip?

Regards

Manfred

Dragging a RadTitleBar

Is there a way to know when a user is dragging a RadTitleBar around?

I tried to have a ShapedForm with a RadTitleBar, and catch the events in the MouseDown and MouseUp events for the titlebar with the following :

    
            private void radTitleBar1_MouseDown(object sender, MouseEventArgs e)  
        
            {  
        
                if (e.Button == MouseButtons.Left)  
        
                {  
        
                    txtTest.Text = "Down";  
        
                }  
        
            }  
        
            private void radTitleBar1_MouseUp(object sender, MouseEventArgs e)  
        
            {  
        
                if (e.Button == MouseButtons.Left)  
        
                {  
        
                    txtTest.Text = "Up";  
        
                }  
        
            }

The problem is that I don't always get the MouseUp event. I get the event about once every 20 times I tried it. Is there a problem with the mouseup event, or is there another way I can get the info about the start/stop of dragging a form around?
