Every time I use RadWindow e.g:

RadWindow.Alert(new DialogParameters()
            {
                Content = "Hello"
            });

i get following binding error:

System.Windows.Data Error: 5 : Value produced by BindingExpression is not valid for target property.; Value='<null>' BindingExpression:Path=(0); DataItem='RadWindow' (Name=''); target element is 'WindowHostWindow' (Name=''); target property is 'Title' (type 'String')

I even tested it on visual studio base wpf app template - still the same error.

Is there any way to fix it ?

Hi,

I'm using VS2008 and Telerik 2011.3.1220.35 and with one of my RadGridView I have a problem :(

The second column of my grid view is a GridViewToggleRowDetailsColumn and when I click on the plus sign, my application fall in an infinite loop and I receive the following message:

Here is my XAML RadGridView definition:

how can delete time and convert format to dd/MM/yyyy?
when i want edit date cell its format is dd/MM/yyyy but when i want only see its format is MM/dd/yyyy.
can help me?
thankful.

In our view model we are clearing out an observerable collection (Schedule.Clear()) while a cell grid is in edit mode and we are getting the following exception.

Any ideas? We have a workaround for now where assign a new observable collection to the property but would rather clear.

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

Parameter name: index

I am working with Telerik WPF controls, RadGridView, RadDataPager and VirtualQueryableCollectionView<T>.
The PageCount of RadDataPager is incorrect once i filtered the data via RadGridView header. The PageCount  is  
always 1.  please find attached image screenshot.

I do not know how to fix this issue. In following code, i set the VirtualItemCount value as new value but the RadDataPager show me 1 as PageCount. I could not move to next page.  

Assembly version is: 2011.3.1220.40



 

Hi,

On a button click, is it possible to invoke a telerik datagrid column chooser context menu in WPF?

A code snipped will be appreciated

Thanks,

Hi,
I am trying to create a program that will have a listbox on the left of database table names and then a grid area to the right.

When the user double clicks on a table name  a grid with the table data should be populated with the table data. Once it is open the user should be able to make changes and hit the save button that will submit the datacontext changes.

I have a linq to sql set up for the Northwind database for this example.

As soon as I make a change in the grid to a cell the entire row disappears??? not sure what I am doing wrong.

Thanks,
Jessica 

I am using RadRibbonWindow to host a RadRibbonView, and set QuickAccessToolBarPosition to "AboveRibbon", but the QuickAccessToolBar is overlaying the application icon.  How can I shift the QuickAccessToolBar away from the application icon?  
I like to have the same format as Excel 2010 which has a separator between the application icon and the QuickAccessToolBar (please see the attachment).

Thanks.

Hello,

I recently updated my application to the 2011 Q3 DLLs. I have a tab control that binds to an ObservableCollection for the ItemsSource. I have to add an item to the ObservableCollection in code. I used to be able to do an UpdateLayout on the tab control, and it would add the new tab. It doesn't do this anymore. I can set the ItemsSource to null and back to the ObservableCollection to get the tab to show up, but that has other very bad consequences in my application.

Have you seen this problem with the UpdateLayout not working? Do you know of a work around?

Thanks,
Scott

Is there a way to define an item minimized in xaml (so that it appears in the minimize area by default)?

My list is only 3 items and it looks silly to not have any items in the minimized area (using office_blue theme), so I'd like to push my third item there by default (since it's importance is less, it can be hidden away by default).
