Hi, Telerik,
I am developing for WPF Prism application on .Net 5.
I need to provide an editor functionality which is in MS Word.
I found Perlom's question here and have read it but, I can't have any clue.
How can I solve this problem?
For your information, I am going to attach an image file captured Perlom's question.
TIA

Hello. I'm using a RadTabControl with statically declared RadTabItems in the XAML. Within a RadTabItem, I am using a RadTabItem.HeaderTemplate to define the item's header to include an image. Immediately following the HeaderTemplate, I put a reference to another View (a UserControl). I've included the XAML for the RadWindow which contains the TabControl I am referring to below.
Here's my question. I am looking to load data when a new TabItem is selected, instead of loading data in the constructors of my VIewModels (so that I am not loading a ton of data when the app launches). So, for example, I don't want to load the data within Manifests_Home_ViewModel until the user has selected the Manifests TabItem. But, as you can see in my XAML, a reference to my UserControl
<mainWindow:Manifests_Home_View />is nested within the first tab item of a TabControl on my MainWindow View. But the Manifests_Home_View doesn't know anything about the parent View (MainWindow) that is is nested in. Since the TabControl is on the MainWindow, I don't know how to inform this child/nested view that its parent TabItem has been selected.
I'm fairly new to MVVM and am still converting parts of my app properly to MVVM. I found some stuff about hierarchies with Views/ViewModels and MVVM, but that was more about dynamically generated/injected Views. These aren't dynamic as such, as they are defined up front. They are simply split out into multiple views for organization and cleared code.
Thank you for your help.

Hi,
This is bit outdated question, but I want to handle GridviewRow double click event more efficiently.
My grid view contains RowDetails template (Tab control). Row details contains summary and attachment tab. While attachment tab displays attachments in girdview control.
I had registered GridviewRow double click event in parent GridView as
private void GridView_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
{
if (e.Row is GridViewRow)
{
e.Row.AddHandler(GridViewRow.MouseDoubleClickEvent, new MouseButtonEventHandler(OnRowMouseDoubleClick), false);
}
}Double click event is fired as expected but with following exception (which is not required), but as per behavior its valid.
- Double click event triggered by double click on parent gridview header
- Double click event triggered by double click on GridviewRow details (even scroll bar in attachment gridview)
To overcome these I added following checks
private async void OnRowMouseDoubleClick(object sender, MouseButtonEventArgs args)
{
FrameworkElement originalSender = args.OriginalSource as FrameworkElement;
var cell = originalSender.ParentOfType<GridViewCell>();
if (cell == null)
{
return;
}
var selectedRowContext = ((System.Windows.FrameworkElement)sender).DataContext as MyDataContext;
if (selectedRowContext == null)
return;
}
Basically I am validating Gridview Header and RowDetails gridview scrollbar by "cell" in above example.
While I validate Row details double click by selectedRowContext as there datacontext is different from MyDataContext.
I feel that this is temporary solution. I want to fix it, i.e. double click only happens on DataRow or Data cell. All other controls in Gridview should be excluded.

Hello,
I want to be able to filter (and also see what I am filtering) when the IsEditable Property of the RadComboBox is false
Is there a way to set a Textblock in the Itemtemplate (like the ClearAll Button) of the RadComboBox to filter through the Items?
Regards,
Kai

I can see event handlers for Move and Remove a point on a connection but not for add. There's code for ConnectionManipulationStartedCommand and ConnectionManipulationCompletedCommand which gives us move and remove but is there one for adding a point?

Hi All!
I solve the problem to disable of some RadPanes to drop on a specific RadPaneGroup. RadPane groups are created in xaml with a defined Name (also Tag has been tested):
<telerik:RadSplitContainer InitialPosition="DockedLeft">
<telerik:RadPaneGroup x:Name="Left"/>
</telerik:RadSplitContainer>
In a custom docking panes factory the each RadPane (Tag contains position - string, e.g. Left) is correctly added into the specific RadPaneGroup based on the Name specified above. All the RadPanes are correctly added.
protected override void AddPane(Telerik.Windows.Controls.RadDocking radDocking, Telerik.Windows.Controls.RadPane pane) { var tag = pane.Tag.ToString(); if (radDocking.SplitItems.ToList().FirstOrDefault(i => i.Control.Name.Contains(tag)) is RadPaneGroup paneGroup) { paneGroup.Items.Add(pane); } else { base.AddPane(radDocking, pane);
} }
OnPreviewShowCompass event is used to allow a RadPane to drop on a specific RadPaneGroup. However, in the argument of this method (PreviewShowCompassEventArgs e) the Name property in e.TargetGroup is empty. But a given TargetGroup (RadPaneGroup) contains the correct number and types of RadPanes.
I cannot understand why Name property is empty, it should be specified based on xaml and a reference to this should be taken.
Thank you.

Hi!
I would like to have a scatterpoint series with horizontal lines as point template.
Moste important: the width of these horizontal lines must be the width of the ticks on the horizontal axis.
It is supposed to look like a StepLineChart where the verticalrisers are transparent so to speak, so the horizontals forms steps.
