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This is bit outdated question, but I want to handle GridviewRow double click event more efficiently.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.

Hi team,

We are working with a requirement where user would only wants to enter date for the selection and control suggest current month and year.

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

This is what it looks like in the PDfViewer.Some characters are not shown.  '成'  Unable to display。

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.

Have a RadGridview that allows multiple selections. Currently only allowing rows.

If you select row 1, 4, 6 - 10 and 20, do a Ctrl+C then a Ctrl+V in a text file or excel all the rows between the numbers are blank.

Not sure what feature needs to be included in the XAML to prevent this behavior. Or what must be done short of modifying the collection in the clipboard.

sample of result is:

Does the RadTimeBar support when Windows has a non-Gregorian calendar set? Specifically this one: https://docs.microsoft.com/en-us/dotnet/api/system.globalization.umalquracalendar?view=net-5.0. I get an exception that says this when I change my Windows settings to get that calendar:

Exception Stack Trace: System.Windows.Markup.XamlParseException: Specified time is not supported in this calendar. It should be between 04/30/1900 00:00:00 (Gregorian date) and 11/16/2077 23:59:59 (Gregorian date), inclusive.

I can reproduce it with XAML as simple as this:

		<telerik:RadTimeBar x:Name="TimeBar"
                            PeriodStart="1-Jan-2019 12:00:00 AM"
                            PeriodEnd="31-Dec-2019 11:59:59 PM"
                            VisiblePeriodStart="14-March-2019 12:00:00 AM"
                            VisiblePeriodEnd="11-Nov-2019 11:59:59 PM">
			<telerik:RadTimeBar.Intervals>
				<telerik:YearInterval />
				<telerik:MonthInterval />
				<telerik:WeekInterval />
				<telerik:DayInterval />
			</telerik:RadTimeBar.Intervals>
		</telerik:RadTimeBar>

Hello

I am using it by making a ViewModelBase class by default.

I looked at Telerik's ViewModelBase class documentation and this is not what I'm looking for.
https://docs.telerik.com/devtools/wpf/common-information/mvvm-helpers/common-viewmodelbase-class

I prefer to display getter setters on one line.

using Telerik.Windows.Controls;
private object item;
public object Item 
{ 
        get => item;
        set 
        { 
                item= value; 
                RaisePropertyChanged(); 
        } 
} 

// Create ViewModelBase helper method
protected virtual bool SetField<T>( ref T member, T newValue, [CallerMemberName] string propertyName) ... ... 

private object item;
public object Item
{
    get => item;
    set  => SetField(ref item, value);
}

If that doesn't work, I'll continue to create and use my ViewModelClass.

Thanks.
