Hello,

I was going over the documentation page for a combo box column in a RadGridView.  The "one click" solution shows adding styles to the Column definition in XAML to set "OpenDropDownOnFocus" to true.

Is there a way this can be accomplished in code?  I am using the NoXaml binaries.  I tried the following:

But when the grid renders now, the dispaly works, but the editor for the combobox columns no longer have content. 

Since I'm using the NoXaml binaries, do I need to explicitly define the EditorTemplate as well because the EditorStyle overrides the implicit template?

I am not sure whether this should be classed as a bug or not.

When using the VisualStudio2013 Dark Theme and closing a RadWindow it "Shrinks" and fades away. However the window is still active whilst it is shrinking.

In my use case I have a RadWindow as a popup with a RadListBox containing several items. On the RadListBox's SelectionChanged Event some work is carried out and I call Close() on the RadWindow. This happens very quickly and if a user double clicks a RadListBoxItem rather than single clicking the RadWindow it is already closing and the RadListBoxItem below the selected item moves under the curser as the RadWindow "Shrinks". This item then fires the same event.

As a work around I am going to set IsEnabled=false on all my RadWindows before calling Close() as this fixes the issue.

I just wondered whether this could effect other peoples projects in different ways, and whether the IsEnabled=false should be set somewhere else within the Telerik code as an automated process.

Regards,

Shaun

WPF Telerik RadGridView disappeared when i applied global style.

If i remove the below part from GridViewStyle.xaml, the grid appearing fine, but i want to configure those settings globally.

I am using Interaction triggers to Data bind the Data filter event to Relay commands in view model, I can do this for FilterOperatorsLoading event that is directly in DataFilter but i need to listen to 2 other events that are in FilterDescriptors.

This event works:

<i:EventTrigger EventName="FilterOperatorsLoading">
                    <cmd:EventToCommand Command="{Binding FilterOperatorsLoadingCommand}" PassEventArgsToCommand="True" />
</i:EventTrigger>

How can do that same for RadDataFilter.FilterDescriptors.CollectionChanged and RadDataFilter.FilterDescriptors.ItemChanged event

Thanks

Good afternoon,

In each page of our WPF application we have a few user controls from the Telerik library. We're running the Visual Studio profiler and noticed that for each UC from Telerik, all the themes are being parsed at runtime, as it can be seen from the screenshot attached or at this link.

The theme is being explicitly set at the beginning of the app and we haven't been able to find any help/documentation on this matter.

We would like to prevent this additional render time for each control to achieve the most fluid UI we can.

Any help would be appreciated.

Thanks in advance,

Diogo

Hi to all,

I have this problem in design-time, sometimes it appears this error when I show a GridView.

My XAML is this:

Hi!

Is there any fast/easy way to change the expander image of RadExpander like expander of TreeListView?

Thanks!

Hi,

We are using RadGridView to display data from the DataTable. In one of the column we have selected "StartsWith" has the filter. After setting the filter if we close and re open the view, we are getting the following error and the application crashes. This is once we load the layout even before Data is loaded.

System.NotImplementedException: The method or operation is not implemented.
   at Telerik.Windows.Data.Expressions.FilterOperatorExpressionBuilderBase.GenerateStartsWith(Expression left, Expression right)
   at Telerik.Windows.Data.Expressions.OperatorValueFilterDescriptorExpressionBuilderBase.CreateBodyExpression()

   at System.Linq.Enumerable.<OfTypeIterator>d__aa`1.MoveNext()
   at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
   at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)

After digging through the column properties, I found out that FilterMemberType was null. Once I set the property to string type. Its not throwing error anymore.

Please let me know is it the right way to do it or if you have any better solution.

Thanks and regards,

Alex

Hello Telerik,

So far I could get my Grid cells styles to be dynamically changed based on my own roles, using this tutorial

http://docs.telerik.com/devtools/wpf/controls/radgridview/style-selectors/cell-style-selector.html

but there are two things left to be done regarding this issue.

still following the given approach, I want to:

- set an image to a checkbox, whether it is true or false.

- and also set that style in a separate file, so that it may be reused. inside a resourcedictionary file.

My point is, I will have several grids through my application using the same set of styles in their cells. based on each own role.

Please help me to achieve that!
