The RadDataPager works great for us, especially when it comes to speeding up the loading time for our records on the main page of our app (we were loading all of our records at the same time before, and there are a lot of them).

However, is it possible to sort data across pages when you're using the RadDataPager? Currently, when a user clicks on a column header in the RadGridView, it just sorts the records on that page. Would there be a way to sort all of the records across all pages when a user clicks a column header?

I'm assuming that we'll have to implement our own custom logic to get this to work, and I'm also assuming that we won't be able to get around the fact that we'll have to load all of the records in the gridview again, but I'm just wondering if anyone has found an efficient way to do this.

Thanks!

The standard WPF Richtextbox supports pasting of ImageData. Is there a way to get this working with the RadRichTextBox?

I need to make the RadMap pan left/right/up/down based on some non-ui events.  How do I tell the map to pan programatically? Which property do I use?  Is there a RoutedUICommand or something?

I had to do the same thing for zooming and that was pretty easy.  I've found the PanningCompleted event, but don't know where the Pan function is :)  Please point me in the right direction.

Hi,

I'm currently using the RadDocking control in a project.
It's a fairly simple layout with dockable panes on the left of the screen and a document host filling up the rest of the space.

In order to track down this issue I only have 2 panes in the pane group for now.

What I'm trying to do is assign short cut keys to each of the panes.
Specifically, when you press the short cut key for a particular pane that pane will become active and the focus will be on the first control in the pane.

I've defined some RoutedUICommands and used Windows.InputBindings to assign short cut keys to the commands.
The Executed handler for each command does the following:
1. Sets the Selected Item property of the RadPaneGroup to the appropriate pane.
2. Calls control.Focus() on the appropriate control (within that pane).

Unfortunately, this isn't working as it should.

Ridiculously, I've found that by calling DoEvents() in between setting the selected item and setting the focus of the control it works as it should. I know C# doesn't officially have a DoEvents method but if you google it you'll find examples of code that looks like this:

Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new Action(delegate { }));

Obviously, this is a hack and I'm keen to fix it the right way.

Any help would be appreciated, I have a sample application which illustrates the point if needed.

Thanks,

Hi,

I want to know the equivalent mecanism in WPF to bind Property  of the TreeView and TreeViewItems with properties in the ViewModel using MVVM pattern. For Example in silverlight  I do such and work perfectly:


But this one doesn t work in WPF. Can U tell me how to adapt this in the WPF context??

Thank U for your Help

I dynamically built a form using a RadDocking, then a Vertical RadSplitContainer and inside the RadSpltContainer two Horizontal RadSplitContainers. The lower RadSplitContainer has three RadPaneGroups where the right outer contains three RadPanes.
The right outer container is filled like this:

radPaneGroupSystem.AddItem(ucStatusAlarms, Telerik.Windows.Controls.Docking.DockPosition.Top);
radPaneGroupSystem.AddItem(ucRSSFeed, Telerik.Windows.Controls.Docking.DockPosition.Left);
radPaneGroupSystem.AddItem(ucMessageViewer, Telerik.Windows.Controls.Docking.DockPosition.Right);

If I do that I get a "Object reference not set to an instance of an object." error, source "Telerik.Windows.Controls.Docking",
StackTrace   
at Telerik.Windows.Controls.RadPaneGroup.GetPaneGroup()
at Telerik.Windows.Controls.RadPaneGroup.AddItem(RadPane pane, DockPosition dockPosition)

If I change the code and use panegroupParent.Items.Add(ucStatusAlarms), etc I get the three RadPanes as three Tabs functioning normally.

I checked the parameters going into the AddItem call, they are normally set to an instance.
Does anyone know why the Docking gives an Object reference not set to an instance of an object error and what I can do about it?

Hi,

I am using RadGridView with multiple/single field groupings based on conditions. When grid is first bound, it eats away first row of each group, which is event present in the datasource of the grid.

Code for setting default grouping when RadGridView is bound:

Edited: The missing row is restored when I toggle the radio buttons to change the mode (as below)
Below is the code to change the grouping:


Any ideas suggestions on this?

Hi,

I have a WPF application in which I rehost the .Net 4.0 Workflow designer alongside a RadTreeView. Items on the RadTreeView are dragged onto the designer and, when dropped, morph into self configuring workflow activities based on the context from which they were dragged.

I am using Telerik's DragDropManager and the AddDragEnterHandler and AddDragOverHandler methods to add handlers to the Workflow Designer View and that is working perfectly. However...

I need to control the drag cue over the designer and that is proving to be more problematic.

I first tried the following:

However the Designer_DragQueryHandler delegate would never fire.

So I thought it must be that the designer is handling that event before my delegate can be executed, so I tried the following:

This did not work either.

I am at a dead end on this now and would greatly appreciate any direction on how I might achieve this.

Thanks in advance

We are using autogenerated gridview and works fine but we have an issue with rebinding itemssource of filtered (by column default filters) by user.
If you refresh data (we do with background worker as datatable, then set grid itemsource to dataview.defaultview and call grid.rebind()) if the user has set column filters, it looses the ability to remove the filter but still reflects the filter in the grid.
