When I add a right click menu to my grid via the ContextMenuStrip property, it works fine. Except when I right click on the filter bar. Then I get both menus.

Anyone have a fix for this? Other than waiting for the next release?

Hi,
I have a GridView whose datasource is set to a bindingsource. When the application loads, the gridview should be empty because I have not set the datasource of the bindingsource yet. Instead, when I run the application I get an empty HeaderCellElement.
I've looked through your examples and noticed if I want to have the headers expand the entire length of the gridview I have to set the property, AutoSizeColumnMode to Fill. This works great but when I extend a header, the right most ones shrink. How I can make it so that when I extend a header, the others simply push right as opposed to shrinking?
Note: when I stretch a header all the way to the right and then shrink it, only the rightmost column header starts to stretch while the headers in between stay small.
Thank you for all of your help,
Michael

I have a problem which seems to be related to adding a new TabItem to a TabStrip at runtime.
The problem doesn't occur on my computer, or on any other computers I've tested on (which have Visual Studio installed). But when I try running my application on a computer without VS, and without Telerik installed I get a crash:
EventType : clr20r3 P1 : calloperator.exe P2 : 1.0.0.0 P3 : 47a72344
P4 : system.windows.forms P5 : 2.0.0.0 P6 : 4333aefa P7 : 1508
P8 : 12f P9 : system.arithmeticexception
I've limited the crash to this add statement below:
TabItem tab = new TabItem(channel);
tab.Name = channel;
radTabIRCChatStrip.Items.Add(tab);
Do you have any idea what this may be?
PS I have other TabStrips in the same application, but they are not being created at runtime, and they seem to be working fine.

When using a mask on a zip code or phone number and trying to paste into that field I get the error:
Object doesn't support this property or method. When I debug it, it's breaking on your _FakeOnPropertyChange method. Any suggestions?

after reading data for the treeview from database i use a recursive function which sets the image for each node. this takes a very long time because there is a huge tree...
is there a better way to set the same image for all the nodes of the tree?
below i've postet the two functions i use:

Hello,
I'm using the Ribbonbar in my application (Q4 2006 version from VS Express Registration Benefits) on the mainform, which has now many tabs, buttons and other elements on its ribbon.
Using Visual Studio 2008 Pro, the form of my program opened in 1 minute, but after a full reinstallation of my system (Windows Vista Professionnal, 32 bits), I cannot open the mainform of my program anymore.
Whenever I try to open it with Visual Studio 2008, it tries to load it during 5 minutes, with Commit memory constantly increasing up to 1.1 Gb (as shown in Vista's Resources Monitor), and then VS shows an error saying "System.OutOfMemoryException", thrown on a random component in my form.
It seems that there is a memory leak with the designer and the radribbon when it has many items, but I don't know why I could open my project without any problem before and now I can't.
Do you know how I could open my project again ?
Language is C#.
Thank you.

Hi,
I'm trying to prevent a dock panel beeing moved to top or buttom.
My App looks explorer like - but the "navigation pane" can be docked to the right or to the left.
I successfully handled to avoid "float" and other unwanted kinds of the panel.
My next problem was a user dragging the panel arround.
My first approach was to handel DockinStateChanging.
BUT - I always get the previous DockPosition in this event!
My next approach was to handle the already changed state.
BUT - I still get the previous DockPosition in this event!
This means I can't avoid that a user drags the panel to the top position,
since the position shown in the DockingStateChanged handler is the PREVIOUS position!!
So if dragged from left to top - it tells left!
I guess this is some kind of a bug.
Anyhow - is there a way to prevent Top / Bottom docking?
Or at least prevent dragging?
Regards
Manfred

| } |
| if (e.DockObject.DockPosition != DockPosition.Left && e.DockObject.DockPosition != DockPosition.Right) { |
| e.Cancel = true; |
| } |
| } |
My next approach was to handle the already changed state.
| private void rdmMain_DockingStateChanging(object sender, Telerik.WinControls.Docking.DockingChangingEventArgs e) { |

| private void rdmMain_DockingStateChanged(object sender, DockingChangedEventArgs e) { |

Hi
I'm trying to localise the text that appear in the RadGridView but I can only find 3 things back (add, delete row and group) How can I change to other ones, like the text that appear in the filters, to Dutch ?
Thanks
Benny

How do I add a filter value to the grid view programatically?
I have tried several configurations, but I am unable to generate any result. Here is the latest that seemed to make sense to me:
Within the load event
I have tried several configurations, but I am unable to generate any result. Here is the latest that seemed to make sense to me:
Within the load event
'adjust the filtering in the grid to defaults you might want
Me.RadGridView1.MasterGridViewInfo.TableFilteringRow.Cells("active").Value = "true"
Me.RadGridView1.MasterGridViewInfo.UpdateFiltering()
where active is the field name.

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?
