Hello,

How to had the functionality of disable ​Lost Focus ​selected state in RadTreeView ?

In the RadGridView, there is a property EnableLostFocusSelectedState to do that. Why not in RadTreeView ?

Best regards,

Hello,

i am using RadDesktopAlert in my WPF Application on a dual monitor setup. 

I define the alert desktop position by setting the AlertScreenPosition.TopRight parameter.

The alert shows fine however, if my application is on the left monitor because of its StartUpLocation, the alert still shows on my main monitor.

I can't find a property to tell the alert to show on the monitor which contains the mouse. I hope this is possible and you can help me.

Regards,

Hey,

 

I'm occuring something odd. I try to apply a style to a Button. It works fine with just the Button. But the IsMouseOver Trigger doesn't work.

I'm using following code:

<Style x:Key="hyperlinkStyle" TargetType="telerik:RadButton">
            <Style.Setters>
                <Setter Property="Background" Value="#25A0DA"></Setter>
                <Setter Property="Foreground" Value="White"></Setter>
                <Setter Property="FontFamily" Value="Segoe UI"></Setter>
                <Setter Property="Margin" Value="5,5,5,5"></Setter>
                <Setter Property="Padding" Value="5,5,5,5"></Setter>
                <Setter Property="FontSize" Value="12"></Setter>
                <Setter Property="BorderThickness" Value="1"></Setter>
            </Style.Setters>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="true">
                    <Setter Property="Background" Value="Black"></Setter>
                    <Setter Property="Foreground" Value="White"></Setter>
                </Trigger>
            </Style.Triggers>
        </Style>

 

Hope someone can explain why it doesn't work

 

Hi guys,

We are having some trouble with the RadGridView and its ExtentHeight property.
In our application, a RadGridView is displayed and can contain from 1 to 5000 rows.
Some of these rows have a specific state which affects the row style:
- Normal state => row background must be transparent
- Highlighted state => row background must be Red

To help user to identify quickly the highlighted rows, we are showing a "thumbnail view" left to the grid view.
This "Thumbnail view" shows a white vertical bar which contains Red rectangle for each highlighted rows. Over this vertical bar, a "Zoom Box" rectangle is displayed to indicate which part of the table is currently visible in the viewport (see image).

We are trying to synchronize the position of the "Zoom Box" with the Vertical Offset of the RadGridView. Right not it is more or less ok when using the mouse wheel (either in the RadGridView or in the "Thumbnail View").
But it's not working properly in the following case (Zoom Box is out of sync):
- Dragging TOO FAST the scrollbar position indicator (if the RadGridView was completely scrolled using the mouse wheel before, then it works)
- Clicking somewhere in the "Thumbnail View"

After analysis we think that this problem comes from the ExtentHeight property of the RadGridView.
As we understand at the beginning, the ExtentHeight property is estimated using the "real" height of each visible rows and the default height for all other rows.
Then when the RadGridView is scrolled, the ExtentHeight property is adjusted with the "real" height of each new visible row.

Is there a way to override the ExtentHeight of the ScrollViewer of the RadGridView ?
Or another way to accomplish this synchronization?

I have added a sample project.

Thanks for your assistance,
Kind regards,
Benoît

I try to install Telerik UI for WPF Demos but it fails.

I am on Windows 10 with Visual Studio 2015.

In attachment you have a screenshot with the detail.

I have the problem, that my currently highlighted row is not visible, if it is under a selectedrow. For example if i have a gridview with 10 rows, and 5 of them are selected. If i navigate up and down in the grid with the arrow keys, the heighlighted row is only visible in not selected rows. What can i do here? It's seems to be an "z-order" problem or some thing like this.

 Thank you!

Hello,

I have some graphical problems / questions with RadRibbonWindows / RadRibbonView in my application :
I use implicit theming.

• In attached file "Ribbon01.jpg", in some themes like Office2013, there is no margin at left and right of ApplicationButtonContent ? The following RadRibbonTabs have margin in the header.
• In attached file "Ribbon01.jpg", the ComboBox(s) have not the good style.
• In attached file "Ribbon02.jpg", the contextual group do not cover the size of the RadRibbonTab header.
• In attached file "Ribbon03.jpg", the title bar of theme "Windows Touch 8" is not correct.
• Is there a static resource in Telerik RibbonView DLL that provide a background brush for the window content.

Best regards,
Geoffrey

Dear support,

I have three TreeListView-components next to each other. Every one of them shows a part of the same data (scrolling and expanding is synchronised between these three treelistview). So only the most left component has to show the indent-indicator (the black triangle). How can I hide the indicators of the other two TreeListViews?
 

Thanks in advance

Marcus

If you are using a HeaderTemplate and save the layout, when the layout is loaded next the headertemplate is blown away and replaced with a TextBlock.  Title works just fine and is able to apply it's template.

 

I believe the code bug is in DockingLayoutFactory.cs in the RadPane LoadPane(XmlReader reader) method

 

 public RadPane LoadPane(XmlReader reader)
        {
            string name = reader.Name;
            Dictionary<string, string> attributes = ReadAttributes(reader);
            RadPane elementByTypeName = null;
            if (attributes.ContainsKey("SerializationTag"))
            {
                elementByTypeName = this.docking.NotifyElementLoading(attributes["SerializationTag"]) as RadPane;
            }
            if (elementByTypeName == null)
            {
                elementByTypeName = this.GetElementByTypeName(this.docking.GeneratedItemsFactory, name) as RadPane;
            }
            if (elementByTypeName == null)
            {
                throw new InvalidOperationException();
            }
            if (attributes.ContainsKey("SerializationTag"))
            {
                RadDocking.SetSerializationTag(elementByTypeName, attributes["SerializationTag"]);
            }
            ReadProperty(attributes, elementByTypeName, RadPane.IsPinnedProperty, "IsPinned", boolParser);
            ReadProperty(attributes, elementByTypeName, RadPane.IsHiddenProperty, "IsHidden", boolParser);
            ReadProperty(attributes, elementByTypeName, RadPane.TitleProperty, "Title", identityParser);
            ReadProperty(attributes, elementByTypeName, HeaderedContentControl.HeaderProperty, "Header", identityParser);​

The above line should most likely read:  ReadProperty(attributes, elementByTypeName, RadPane.HeaderProperty, "Header", identityParser);​

It looks that's why the control template is getting blown away.

 Anyway to get this fixed?
