How should I style the RadMenuItem to get a radio button icon instead of the "check mark" icon.
I want some of my menu items to act as mutually exclusive checkable menu items so I want them to display a radio button.

I want to hide the close button in my alert , i am using version 2015.2.728.45

Hide expansion arrows on rows with no children ?

I have indented child rows that have no children under them, but still have the arrows - they expand into nothing.

How can I hide them ?

Thanks,

Barry

Hi,

we have multiple problems with the performance of the GridView. I have a simple project to demonstrate the problems, but I cannot upload it. Is there any way to do this?

In our application we do not know all the columns at design time, so we have to create the columns at runtime in the code behind.

First performance issue is, after starting the application, if you resize the window, it takes too much time, so you see black parts in the window on resizing.

Next issue was the scrolling. This is acceptable in the sample project, where we set a fixed length and didn't put the grid in a stackpanel or grid, but in our application the grid will be in a docking window and then there is also a poor performance when scrolling.

Next thing is filtering and sorting. It takes about 3 seconds, thats too much.

Are we doing anything wrong with the GridView? We would appreciate any help.

We already read the performance tips and tricks, but it didn't help much.

 

Best regards

Hi,

I have a DocumentHost with a couple of DocumentPanes. When I drag a pane out it becomes a tool window. I want the tool window to have that documentpane inside it when in floating state (Example: Visual Studio). This is achievable in WinForms (Pic attached). Please guide me if it can be achieved in WPF as well.

The cursor doesn't changed when resizing a column.

I don't know, why occurred.

What should I do?

* I am using NoXaml dll file.

  .dll file version is '4.0.30319'.

 

Below my xaml code about RadGridView.

<telerik:RadGridView Grid.Row="1" x:Name="Part_EventListGridView"
                                         AutoGenerateColumns="False" 
                                         VerticalAlignment="Stretch" 
                                         HorizontalAlignment="Stretch" 
                                         ShowColumnFooters="True" 
                                         ShowGroupPanel="False" 
                                         ShowGroupFooters="False" 
                                         ScrollMode="RealTime"                                                  
                                         IsFilteringAllowed="False"
                                         AllowDrop="True"
                                         RowIndicatorVisibility="Collapsed"
                                         >

 

Below my C# code behind.

this.DataContext = ListDataContext;

ctrlEventList.ItemsSource = ListDataContext.EventCollections;

 

Hi,

I would like to

 1-check spell on a string (a sentence in fact)

 2-open spellcheck dialog box only if errors>0 at step #1

 

I can handle the 2nd part=dialogbox and user query ... but likely stupidly, on the first part, I can not find how to test & count errors on a string in code behind :(

 

Any help just for that part would be appreciated,

Hi,

I'm using RadCartesianChart, which has ScatterPointSeries, the series displays a huge number of points (around +60,000). The point template contains a path representing the visual of the point (The template is included in this post)

it takes around 20 seconds just to display the chart, and when I zoom in, the UI freezes for around 10 seconds and what makes it worse is these points are clickable.

Is there any way to display this much of point with good performance? I'm already using these rendering options (SnapsToDevicePixels="False" RenderOptions.BitmapScalingMode="NearestNeighbor")

<telerik:ScatterPointSeries.PointTemplate>
                        <DataTemplate>
                            <Path x:Name="PointMarker" 
                                            Stretch="Fill"
                                            Height="17"
                                            Fill="LightCyan"
                                            Stroke="Gray"
                                            StrokeThickness="1"
                                            Width="17"
                                            DragEnter="OnBasePointDragEnter"
                                            Drop="OnBasePointDrop"
                                            Tag="{Binding DataItem}"
                                            Data="F1 M 6.5,3.5 L 3.5,0.5 0.5,3.5 3.5,6.5 0.5,9.5 3.5,12.5 6.5,9.5 9.5,12.5 12.5,9.5 9.5,6.5 12.5,3.5 9.5,0.5 6.5,3.5 Z" />
                        </DataTemplate>
                    </telerik:ScatterPointSeries.PointTemplate>

Hi,

Lets's say I have a TreeListView as such:

Group #1

     Item 1-1

     Item 1-2

Group #2

     Item 2-1

     Item 2-2

 

I need the user to be able to select one or both items under a Group - but NOT the group itself (there's reasons for it, that I don't need to get into).

How would I do that ?
