I am using the RadTimeSpanPicker to choose a duration, and I'd like to style the Clear and Close buttons to match the Run New Objective button.  How can I access the button styles?

Thanks,

Using 2024.1.423 PivotGrid and PivotGridFieldList, when trying to do a row filter on a column that has null values, Telerik.Windows.Controls.FieldList.Editing.Selectable.GetHashCode() will error with a NullReferenceException.  This works when doing a label filter on a row or column though since the pivotgrid and the PivotGridFieldList use different methods of getting the distinct values.

Any way to fix it without having to modify the underlying data?

Thanks,

When the user is using the MultiColumnComboBox, if they open the combo box, then use the arrow keys to highlight a row in the grid, but then change their mind and hit escape to close the dropdown, then want to move to the next field so they hit tab, it then selects the last record that was highlighted in the grid. This seems like a bug to me. The docs for this control say "Escape: Pressing Escape will close the DropDown and the matched item would not be selected."

If the user can't tab out of the field without selecting a record, how can they leave the field without selecting a record with just the keyboard?

I was able to duplicate this functionality in the demo app. See zipped GIF in the attachments.

Hello Telerik Team,
We have a close button in RadTabItem and all the tab items are added from the list in the ViewModel.
On clicking of the close button, the particular item will be removed from the list in the ViewModel that reflects in the UI.
Here we are having a scenario in which if the RadTabItem content is heavily loaded, then it takes more time to close.
Please suggest a way to avoid the performance issue while closing the RadTabItem.

The Telerik Version we are used are 2023.2.718

Thanks and Regards,

Hi,

If I select multiple rows in a table in a RichTextBox, the delete options become un-selectable. How can I change this to enable me to delete multiple selected rows from a table?

I've been pulling my hair out on this forever.  I'm developing an application that has items with custom fields.  Sometimes the user will choose an option from the custom field, sometimes they'll leave it blank.  I'm trying to get a RadComboBox to display the selected item only if the item is not null.  If the item is null, then the combobox should display nothing (or a notice it's blank).  

   What's happening is either the combobox does not keep in sync, or it defaults to the first item in the collection.  I need it to be in sync, but not default to the first item in the list if the property is null.  For example simplified view of my ViewModel:

Class CustomField:  Id as Integer, Description as String

ViewModel:

  Public Property Selection as CustomField
  Public Options as ObservableCollection(Of CustomField)

WPF:

        <telerik:RadComboBox x:Name="rcbDropDown" 
                             ItemsSource="{Binding Path=Options}"
                             SelectedValuePath="Id"
                             DisplayMemberPath="Choice"
                             SelectedItem="{Binding Path=Selection, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                             ClearSelectionButtonContent="Clear"
                             ClearSelectionButtonVisibility="Visible"
                             IsEditable="False"
                             IsReadOnly="{Binding Path=IsReadOnly}"
                             EmptyText="Not Set"
                             UpdateSelectionOnLostFocus="True"
                             />

I've tried multiple combinations of SelectedItem Mode=TwoWay, OneWayToSource and IsSyncronizedWithCurrentItem=True/False/NULL

   I either end up with them syncing and the combo box defaulting to the first item on the list automatically, and pushing that into the viewmodel when the record is viewed, or not syncing.  I can't get it to only show the selected item when it's not null.  Any help would be appreciated!

Hello everybody,

in my WPF Application I am using Telerik's RadGridView. Everything is working fine so far.

But there is a little design issue, I am facing with.

In my App I am using Windows11Theme, if I use this, every row in my GridView is starting with a blue column. Sadly I am not able to find out, how to change this color.

Previously, I was using Windows8Theme and there I used "StrongColor" property to change this color. But I am not able to find out, how to change it in Windows11Theme.

Attached is an image, which shows the row, I want to change.

Thanks for your support.

BR,

Alex
