I'm trying to use RadPrompt (and RadAlert/RadConfirmation) in a WPF app using Prism. I have followed this guide: https://www.telerik.com/support/code-library/integrating-raddialogs-(confirm-alert-prompt)-with-prism's-interactionrequest-using-mvvm . At the point I raise the interaction request, I can see that the RadWindow.Prompt gets called (and it's Owner is set to the calling Window), but no prompt window shows. I can't interact with the owner window so that suggests the prompt does exist, it just doesn't appear to have any visual element. What might I be missing here?

Bug when using with IME

When using AutoCompleteBox with IME, the AutoCompleteBox may "steal" characters from the IME input.

For example, if there is an auto complete entry named "Hello", and we type "HA" in the AutoCompleteBox with an IME, the initial character "H" will be stolen by the AutoCompleteBox, leaving only "A".

The label and data entry fields are different from the template alignment of the sample.

I want DataForm to have a default alignment. However, the default alignment does not appear as sample as shown below. It is not known that the item can also be set from the attribute. I want to know how to change the settings.

RadGridView with custom column cells, multiple item selection, and right menu click

Hello everyone!

I'm currently not sure how to implement a solution for this problem. I want a RadGridView which has the ability to select multiple items whether it's shift or ctrl clicks, but I once the items are selected, I want the user to be able to right click and make a selection in a menu. For instance, if a grid column is just a column to designate colors of each item, the user can select in the menu, change color and a window pops open and then they can select the color. Once the color is selected, then all the items that the user selected would be changed to that color. I understand I should use the RadContextMenu, but I'm not certain on how to use it with multiple selections.

Also, how can I make a custom column? For instance, I could just have a rectangle that would fill up and items cell and be a randomized color?

Thanks!

Remove Color from RadPane

Hi,

I am quite new to both Telerik and XAML.

I am testing out Telerik controls and trying to create a simple application.

So far it is going ok, I have managed to create the layout I want, however there is a small thing bugging me. The color of the Header changes when a Pane gets focus. I am using Docking to define my application layout, and thus I don't really need this color change. Also, it appears the styles are different from when the RadPane is included in a DocumentHost or not.

My code looks like this:

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

<RowDefinition Height="*" />

</Grid.RowDefinitions>

<StackPanel Orientation="Horizontal">

<telerik:RadMenuItem Header="Fil" />

<telerik:RadMenuItem Header="Om" />

</StackPanel>

<telerik:RadDocking Grid.Row="1" >

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadPane Header="Applikation" CanUserClose="False" CanFloat="False" CanUserPin="False" ContextMenuTemplate="{x:Null}">

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer InitialPosition="DockedLeft">

<telerik:RadPaneGroup>

<telerik:RadPane Header="Menu" CanUserClose="False" CanFloat="False" CanUserPin="False" ContextMenuTemplate="{x:Null}">

<telerik:RadTreeView>

<telerik:RadTreeViewItem Header="Sport Categories" IsExpanded="True">

<telerik:RadTreeViewItem Header="Football" IsExpanded="True">

<telerik:RadTreeViewItem Header="Futsal"/>

<telerik:RadTreeViewItem Header="Soccer"/>

</telerik:RadTreeViewItem>

<telerik:RadTreeViewItem Header="Tennis"/>

<telerik:RadTreeViewItem Header="Cycling"/>

</telerik:RadTreeViewItem>

</telerik:RadTreeView>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

<telerik:RadSplitContainer InitialPosition="DockedBottom">

<telerik:RadPaneGroup>

<telerik:RadPane Header="Output" CanUserClose="False" CanFloat="False" CanUserPin="False" ContextMenuTemplate="{x:Null}"/>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

</Grid>

So want I want is either to remove the heading color altogether (as seen in the attached screenshot where "Menu" is blue) or change "Applikation" to have the same behavior as "Menu", i.e. is not underlined, but have a solid heading when in focus like the one "Menu" has.

Best regards

Andreas

DragDrop between GridView and child GridView in HierachyChildTemplate

Hi,

I am developing a control which contains a GridView. Some of the items can have sub items which are assigned to another GridView which is the HierarchyChildTemplate of the main GridView.
How can I implement a drag and drop functionality between the main GridView and the child GridView and vice versa.

Thanks.
