Is there any way to implement Excel-style "Delete" key behavior for selected cells in RadGridView? I want the Delete key to clear the selected cell's contents, setting the underlying data-bound property value to null or whatever the default value of the databound type is.
I haven't been able to find any info on whether this is possible-- somebody posted a related issue in 2010 (http://www.telerik.com/forums/cleaar-the-cell-content-at-runtime) but it does not appear to have been resolved.
Could someone please help me implement this behavior? I'm currently trying to override the delete key in a custom KeyboardCommandProvider but none of the RadGridViewCommand options do what I want.

Hey telerik,

 

My grid's external spinner (RadBusyIndicator) won't work when grouping the grid. It works only when loading data.

Here is some sample code illustrating my scenario:

<telerik:RadBusyIndicator Name="busyIndicator" IsBusy="True" DisplayAfter="0">
           <telerik:RadGridView Name="RadGridView"  ItemsSource="{Binding View}" IsReadOnly="True" Style="{StaticResource VitorStyle}"  AutoGenerateColumns="False">

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            ((ViewModel)DataContext).Load(complete);
            var view = (DataContext as ViewModel).View;
            view.ItemsLoading += View_ItemsLoading;
            view.ItemsLoaded += View_ItemsLoaded;
 
 
            //the spinner wont work for the grouping.
            //this.RadGridView.Grouping += RadGridView_Grouping;
            //this.RadGridView.Grouped += RadGridView_Grouped;
            //this.RadGridView.GroupRowIsExpandedChanging += RadGridView_GroupRowIsExpandedChanging;
            //this.RadGridView.GroupRowIsExpandedChanged += RadGridView_GroupRowIsExpandedChanged;
        }
        //private void RadGridView_GroupRowIsExpandedChanged(object sender, Telerik.Windows.Controls.GridView.GroupRowEventArgs e)
        //{
        //    this.busyIndicator.IsBusy = false;
        //}
 
 
        //private void RadGridView_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e)
        //{
        //    this.busyIndicator.IsBusy = true;
        //}
 
 
        //private void RadGridView_Grouped(object sender, GridViewGroupedEventArgs e)
        //{
        //    this.busyIndicator.IsBusy = false;
        //}
 
 
        //private void RadGridView_Grouping(object sender, GridViewGroupingEventArgs e)
        //{
        //    this.busyIndicator.IsBusy = true;
        //}
 
 
        //B)
        private void View_ItemsLoading(object sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e)
        {
            this.busyIndicator.IsBusy = true;
        }
 
        private void View_ItemsLoaded(object sender, VirtualQueryableCollectionViewItemsLoadedEventArgs e)
        {
            this.busyIndicator.IsBusy = false;
        }

public class ViewModel
{
    public VirtualQueryableCollectionView View { get; set; }
    Controller controller;
 
    public ViewModel()
    {
        controller = new Controller();
    }
    public void Load(bool complete)
    {
        //G the virtual queryable collection. this is the Key Class telerik grid needs to perform the Infinite scrolling. or virtualization.
        View = new VirtualQueryableCollectionView(controller.GetList(complete)) { LoadSize = 10 };
    }
 }

 

This spinning issue has been troubling me for quite some time by now.

It won't show on grouping, sorting and filtering.

 

please send a light

 

Thank you!

Hi to all,

I create a docking, when add new usercontrol, I insert a new RadPane that contains the usercontrol selected, ok.

After I add other one usercontrol, docking activates my last usercontrol, ok.

In my 2nd usercontrol I have gridview, apply filter by filtersearch.

Click on 1st usercontrol (first radpaneheader),

after that, click again on 2nd, my filter is cleared, and gridview reload all data.

Can I disable this behavior?

I am currently upgrading our customer Aplication from Telerik UI for WPF version 2010.3.1314 to Telerik UI for WPF version 2016.2.613

Currently I am upgrading RadScheduler to RadScheduleView in XAML file.

  • ViewMode="Day"
    ===> ActiveViewDefinitionIndex="0"
    <telerik:RadScheduleView.ViewDefinitions>
        <telerik:DayViewDefinition/>
        <telerik:MonthViewDefinition/>
        <telerik:WeekViewDefinition/>
        <telerik:TimelineViewDefinition/>
    </telerik:RadScheduleView.ViewDefinitions>
  • AppointmentTemplate="{StaticResource AppointmentTemplate}"
    ===> AppointmentItemContentTemplate="{StaticResource AppointmentTemplate}"
  • SelectedViewStartDateChanged="_RadScheduler_SelectedViewStartDateChanged"
    ===> VisibleRangeChanged="_RadScheduler_SelectedViewStartDateChanged"
  • SelectedTimeSlot="{Binding Path=SelectedTimeSlot,Mode=TwoWay}"
    ===> SelectedSlot="{Binding Path=SelectedTimeSlot,Mode=TwoWay}"
  • IsReadOnly="True"
    ===> SpecialSlotsSource="{Binding EventSlots}"
  • IsViewModeNavigationEnabled="True"
    ===> NavigationHeaderVisibility="Collapsed"
  • MonthViewScrollBarVisibility="Collapsed"
    ===> ???
  • CalendarVisibility="Visible"
    ===>???
  • DisplayEmptyGroup="False"
    ===><telerik:RadScheduleView.GroupDescriptionsSource ShowNullGroup="False">
            <telerik:GroupDescriptionCollection />
            </telerik:RadScheduleView.GroupDescriptionsSource>
  • ActiveViewDefinitionChanged="_RadScheduler_ActiveViewDefinitionChanged"
    ===>AppointmentSelectionChanged ="_RadScheduler_ActiveViewDefinitionChanged"
  • TimeSlotTemplateSelector="{StaticResource SelectTemplate}"
    ===>AppointmentItemContentTemplateSelector="{StaticResource SelectTemplate}"

I cannot run the program yet because of a large number line of code in project.

Please help me to review my modify source code, expecialy how to migrate MonthViewScrollBarVisibility="Collapsed" and  alendarVisibility="Visible". 

Thanks,Liem.

Hi,

RadGridView behavior after update/insert row is different between NewRowPosition="Top" and NewRowPosition="Bottom".
When position is defined "top", after saving the scroll is on the same position as before saving. However, when the position is defined "Bottom", after saving it scrolls to top.
Workaround with ScrollIntoView() is not useful in my case, because I may have many rows updated.
How can I achieve the same behaviour as NewRowPosition="Top" after saving?

Thanks

On the left of the grid records there is a gray area of a few pixels, is there any way to remove this so that the records data is directly left-aligned against the edge of the grid?

Hi,

I am new to using Telerik Framework. I am trying to write automated tests for a WPF application that we have, but I keep getting a null reference exception when I try and use the code described in this page http://docs.telerik.com/teststudio/testing-framework/write-tests-in-code/silverlight-wpf-automation-wtc/wpf-ui-automation. 

 

This happens in the line that is launching the application 'WpfApplication foo = myManager.LaunchNewApplication(@"C:\Users\e-ddcr\Documents\GAV\2.0\gav-app\PokeMoon\PokeMoon.Startup\bin\Debug\PokeMoon.Startup.exe"); '. Unfortunately the error does not seem to give me very much to go on, and I could not find anything online that helped resolve the issue. 

Below you have the details of the error and my code. Any help would be hugely appreciated.

 

Many thanks,
