Hi,

I would like to bind the visibility property of an annotaiton to a property of my DataContext binded to a checkbox.
It seems that setting the Visibility property of an annotation has no effects.
Is it a bug ? Do i need to remove it from annotation's collection and reinsert it ?

Regards.

I've created a DropDownButton which has a sequence of checkboxes and a ok/cancel button pair in the dropdowncontent. The dropdowncontent is not supposed to close unless I click one of the buttons, hit escape, return or click outside the dropdowncontent.

However, the dropdowncontent closes whenever I click the background on the dropdowncontent - which I do occationally because checkboxes are small and hard to hit when in a hurry.

How do I prevent the DropDownContent from disappearing when I click it's background (that is, the grid which holds the entire thing)?

Thanks!

Hello.

I have some custom control (inherits from Control class) and I need to style it as RadWindow (It's need for Mdi window in canvas control). How can I style the control? And how can I save changing theme function on it? Maybe I can use telerik brushes?

Thanks.

I am using version 2012.1.326.35.

I have a RadGridView with a DataTable dt as ItemsSource. The RadGridView appears to render the initial column specification correctly and also recognize the row changes. However, when I update the columns, then I notice that addition and removal of columns are not recognized in the RadGridView.

This is how I refresh my DataTable:

================================================
public void updateData(SomeCustomDataSource data)
dt.Clear();
int num_cols = model.Columns.Length;
for (int i = 0; i < num_cols; i++)
{
SomeCustomColumn c = data.Columns[i];
if (!dt.Columns.Contains(.Name)) // Adding columns not previously existing
{
DataColumn col = CreateDataColumn(c);
dt.Columns.Add(col);
}
}
dt.AcceptChanges();
RefreshGrid(); // Plain old OnPropertyChanged("DataSource");
================================================
I'd like to note that this is just some dummy code. In the actual code I wanted to use, I called dt.Columns.Clear() and re-added every single column on data update. And what happens in that case is that none of the columns changed but when I click on the "click to add new row" row insertion thing, I get a "[Column] does not belong to Table [Table]" ArgumentException, which implies the internal data is not actually refreshed in the RadGridView even though the rows are updated correctly.

Again, if you want my license key in order to provide support, I'd be happy to provide it.

Hello,

we are using Telerik WPF Controls Version Q2 2011 0920.

We have a scenario where we want to programmatically move TileViewItems from one TileView to another. This is done by removing the item from the RadTileView.Items Collection and adding it to the other in code behind.
The issue is that the header is disappearing if we do that (plain text defined in XAML with HEADER Property) and is doesn't come back if we move the TileViewItem back to the original TileView.

Update: Header-Property is correct after the move but the UI isn't showing anything.

Thanks,

Thomas

Hi,

I am seeing two different behaviors from RadGridView control for WPF when I use the SelectAll function from two
different versioned libraries (Version: 2011.3.1116.40 & Version: 2012.2.912.40).

In my example I have a RadGridView which I populate with some dummy data. I have added a RowDetailsTemplate
which is Visible when the row is selected. Everything works consistently in both libraries when the row details are
selected one at a time. But when I make use of the SelectAll function I see that the row highlight is missing with
the new versioned library

When I drag a new appointment onto the schedule view the default length is always set to 1 hour and and I can not adjust it until the OnEndEdit is fired off. Is there any way to adjust this length during either the AppointmentEditing or AppointmentSaving events?

Hi guys,

I have a strange problem, I'm using the telerik wpf docking controls version 2012.3.1203.40 with VS2012 when my touchscreen is connected to my pc by USB (touchscreen: iiyama prolite T2250MTS) the RadDockingAutomationPeer throw an nullreference exception on loading.
If the touchscreen is not connected everything works just fine.

I tried to create a testproject for you, but the testproject throws an ArgumentNullException in the RadTabControlAutomationPeer, in this project I'm not using the RadTabControl.
And again if the touchscreen is not connected everything works fine.

The workaround is easy, just disconnect the touchscreen :-). For now this is my workaround, but it is no solution

Can you check it out?

How do I upload my test project?

David.

telerik RadDocking vs. Prism problems

 

The telerik RadDocking vs. Prism problems are a “show stopper”.  I have invested over fifty hours and cannot get Prism ViewInjection (regionManager.RequestNavigate) to work with telerik RadPanes.

 

Injected telerik RadPane views appear when they are first injected, but the Prism ConfirmNavigationRequest methods are only ever called on the first Injected View.  The same methods on the other ones never fire, and no existing view ever becomes the top view when navigating back.  The top view is ALWAYS the last view injected.  I tried getting a reference from the view model to the view to force the view to the top layer (Bad developer - I know!), but I cannot get a handle to the telerik RadPane views from my view models because they are registered without a Name as a result of using MEF and Prism RequestNavigate.

 

I expected telerik to give me productivity gains, but right now telerik has been a huge drain on my productivity.  In a few more hours I am going to tell my client I cannot get the product built using telerik RadDocking.

We are using VS2010 SP1, .NET 4, WPF, telerik Apr 19, 2011 Q1 2011 SP1 (version 2011.1.0419), Prism 4.

 

Sincerely, Joe
