We have developed a program used by our printing department that allows them to view all letters in a queue, select a few letters, and then print these letters. I'm using the Telerik GridView to display the letters on a WinForm. A BackgroundWorker is being utilized to handle the merging and print processes. Once the worker has completed work we used the worker_RunWorkerCompleted method to refresh the data in my DataAdapter. This seems to be working each time we go through the method. Before leaving the completed method I would like to refresh the GridView with the new data in the DataAdapter. I did this by calling a Delegate to run the following code:

formLetterPrint.radGridView1.DataSource = formLetterPrint.dsLettersToPrint.Letter;

For some reason it will only refresh the GridView the first time we call the delegate. Each time after that it leaves me with a Blank GridView. If I re-sort the GridView my data shows as inteneded. Any ideas?

Change height of panel

Hi.

I am having a problem with the Docking.
This is what I have so far.
I have created a panel (Telerik.WinControls.Docking.IDockable)
This panel is then added to the current panels with the docking manager.

However, I would like this to be separate at the bottom.
So, I have told the docking manager to create a new horizontal tab group (DockingManager.NewHorizontalTabGroup) and given my panel.

This works great so far. It is separated from the other panels, and is at the bottom, however I have two problems that I cannot seem to sort out.

1) (Not critical) I would like to hide the tab at the top of this new horizontal group. It is the only tab that will ever be here, and is just wasting a little bit of space.

2.) (NB) I need to adjust the size of this bottom TabGroup. It is too big (The two tab groups have split the screen 50/50 I think). I need to make it smaller. So that my new TabGroup at the bottom is say 50pixels in height or so... How would I do this?

Thanks,
Kris

Problem with new Property ToolTipText

Hi,

in SP1 we found a new property ToolTipText.
This works when used at runtime.

To reproduce.
Build a WinApp.
Drag a RadPanelbar to it.
At some Elements.
Take the first RadPanelBarGroupElement and enter some text under Properties/ToolTipText

Close the form (in VS) and open it again.

I get the following error messsage:

---------------------------

---------------------------
Error setting property "ToolTipText" in class "Telerik.WinControls.RadItem" to value "TestTT".

The error was:
System.NullReferenceException: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.

bei System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object component, Object value)

bei Telerik.WinControls.Design.RadObjectCustomPropertyDescriptor.SetValue(Object component, Object value)
---------------------------
OK
---------------------------

Change RibbonBar color

Hey,
Is there anyway to change the BackColor of the RibbonBar. I tried to use the RibbonBar.BackColor property but it changed only the ribbon color not the tabs color. I want to change both BackColors.
Thank you

Glitch with radButtonElement Image

When you change the image of a radButtonElement on a ribbonBar, the text does not get pushed over, resulting in the picture appearing behind the text. The only current alternative is to add spaces in front of the text.

Hope this helped.

Release Info correct?

Hi,

in the helpfile I find:
RadDock
New properties

DockContextMenu, ToolTipText properties added in DockPanels and DocumentPane

I found the property TollTipText in the properties.
BUT: using it at designtime produces an error.
http://www.telerik.com/community/forums/thread/b311D-bcbbta.aspx

And I can't find DockContextMenu in the properties.
At runtime I find it - but it is marked as "read only" - so not very usefull.

Regards

FixedSplitters ingnored when AutoHide

Hi,

still messing around with the problem with "ingore minsize"
http://www.telerik.com/community/forums/thread/b311D-bbthde.aspx

I tried to build a "brute force workaround" by disabeling the user to resize the panel when in AutoHide.

I set FixedSplitters (just to check) to true on my docking manager.
This works so far as if with that setting the splitter can no longer be moved.

After setting the left panel to "AutoHide" - I can change it's size :(

To disable AutoHide is not possible since some users have "small" screens where they have to AutoHide to get enough working space in the right panel.

By the - this would bring me to Forms.SplitContaier - which does all the things without errors / bugs --- except the "AutoHide".

It seems to me, as if the DockingManager has a lot of serious problems.
By playing around with it just for a few days I failed to build a very simple layout (Explorer) with some simple settings (MinSize, no ContextMenu, AutoHide).

Since my project has to be finished - it looks as if it is not really possible with this control.
I guess to create my own thing based on "SplitContainer" is less work than trying to overcome the bugs.

What is the correct Assembly Version for Q3 SP1

Hi,

in the last weeks I reported a lot of errors with the controls.

I got in serveral cases the information that this will be fixed with SP1.

BUT - I see no difference (no fix) at all.
So my idea - did'nt I correctly install SP1?

Telerik.WinControls says: v2.0.50727 -- 5.0.3.0.
So do all used controls.

Is this SP1??

Regards
