How to use DockingClientPanelWorkspace

I have just started trying to use the Telerik CAB in a project.

I have looked at the FinanceApplication included in the sample project and managed to put together my own application using the RadDockableWorkspace.

What I want to know is what and how the DockingClientPanelWorkspace is used. My only guess is that it is used in a dockpanel or documentPane.

Thanks

Combobox causes repaint of entire Form

Hello.

I have a RadForm with a lot of controls on it(Multiple radgridviews, radcomboboxes, a tabstrip with radgridviews, etc).
Every time i click any of the radcomboboxes it takes about two seconds of flickering while all controls are repainted, then when i select an item from the combobox, all controls are repainted again.
I have tried using Virualized=True/False, BeginEdit/EndEdit, Populating combobox in Runtime/Designtime in all possible combinations but the behaviour is consistent.

Have I missed anything, how can I solve the problem?

I'm working on a 2GB RAM machine and am only working with small datasets, version of Radcontrols is 2008 Q1 SP1.

Thanks

drag a row from a RadGridView to a ListBox

Hi. I need to drag a row from a RadGridView to a ListBox. How can I do that if I don't have a ItemDrag Event in RadGridView like the one in the ListView? I'm using VB.net.

Thanks

Conditional Formatting based on the value of another cell? Possible?

I'd like to set up a conditional format where I have 2 fields - Quantity Required, and Quantity To Order.

If Quantity To Order is less than Quantity Required, I'd like to have the cell light up and show a red background.

I was hoping I could set up a conditional formatting rule that said if Column A is < Column B then.. etc, but that doesn't seem like it wants to work at all.

What's the best way to go about doing this?

Combobox Dropdown in TabPage

Hi,

I found there is a (I think) similar thread here - but the answer is "find the information in you support ticket" - which does not really help.

My problem:
I have a ComboBox in Radtabstrip.
As usual (custumer employees are used to it - me too) I try to open the CB-list by pressing ALT+DOWN.
What happens?
Tabstrip switches to another page.

I found no setting for "no keyboard nav in tabstrip" or so.

Althoug the setting should be:
Use the well know windos keys for Pagenavigation and keep away the fingers from other predifined key settings :)

What do I mean?
How do you navigate on default windows Tabpages?
CTRL+TAB forward - or CTRL+SHIFT+TAB backwards.
And whatfore ist ALT+DOWN? Yes to open a combobox list.

Anyhow - my problem - I built the app on your control and now I have to implement "default windows behaviour".

So how do I
a.) Disable ALT+DOWN on the tabcontrol so that I can use ist for Comoblist?
b.) How do I change pagenavi to CTRL+TAB (SHIFT+CTRL+TAB)

The first is most important because my customers employees use this combination very often; which means my programm is not usable at the moment for them.

Regards

Manfred

Type of Row Selected

Hello,

How can I get the type of row selected/clicked in radgridview?

I'using a radgridview(master) to show data in another radgridview (detail) evertime that a user clicks in the master radgridview. This works fine when the master radgridview isn´t filtered or grouped.

When the radgridview is filtered or grouped and the user clicks in the (+) symbol to expand de row I get the following error:

System.InvalidCastException: Unable to cast object of type 'Telerik.WinControls.UI.GridViewGroupRowInfo' to type 'Telerik.WinControls.UI.GridViewDataRowInfo'.

The error is generated in the event CurrentRowChanged

How can I detect the type of row selected/clicked or disable that event to prevent this error?

Thank for your support.
LM

RadListBox values

Hi. I need to store two values in each of the items of the radlistbox. I'm trying this:

    
                Class MyItem 
        
                    Inherits Telerik.WinControls.RadItem 
        
                    Public MyShowText As String 
        
                    Public MyStrng As String 
        
                    Sub New(ByVal ShowText As String, ByVal Strng As String) 
        
                        MyBase.New() 
        
                        MyShowText = ShowText 
        
                        MyStrng = Strng 
        
                        Me.Text = MyShowText 
        
                    End Sub 
        
                End Class 
        
                ListBox1.Items.Add(New MyItem(Path.GetFileName(file_name), file_name))

But the listbox is always empty.

Can you help me?

Thanks

First Docked , then AutoHide

Hello,

I am using the DockingManager (6.0.2.0) and set two of the panels DockState-Property to AutoHide. Now the Designer cannot show the form anymore saying "This is not valid state for tabbed document container. Please first change state to Docked and then to AutoHide"

I did change the Designer Code and added the DockState-Property setting to my own Initialize method. But now every time I save the Form, the designer code gets altered back to AutoHide, which means after the next build again I cant see the from in the designer again.

Am I doing something wrong ? Whats the normal way of setting a Panel to AutoHide in the Designer.

Thanks

Dock
