Hi,

We are using telerik radRichTextBox. The version is 2012.3.1129.45.

1. Picture button in ribbon menu
2. Select an image file
3. Use the context menu to "Text Wrapping" and select "Square".
4. Moving the picture with the mouse pointer.

After step 4 the inserted pictures dissapers.
Somtimes it reappers when I insert another picture.

Kind regards

/Andreas

Hi 
I am iterating through the rows and columns of the grid view like this :
foreach (var row in radGridView.Items)
                    {
                        foreach (var column in HeaderInfo)
                        {
                            string sUniquename = uniqueNames[iColumn];
                            var boundColumn = radGridView.Columns[sUniquename] as GridViewBoundColumnBase;
                            if (boundColumn != null)
                            {                                string data = string.Format("{0}", boundColumn.GetValueForItem(row));}
                            iColumn += 1;}}
The thing is that its too slow ...for a grid with say 80k rows it is taking 5 minuted to complete this loop...I guess internally it is building up the rows internally as our grid has virtualization enabled.

Please suggest if something can be done on this.
                        
                    

I got this error while updating the data of schedule view in another thread , not in dispatching thread. Per the exception message, the collection was changed already while it was being enumerated, in line 4625 in ScheduleViewBase.cs, which was triggered in the method OnQueryGoToNextAppointmentCanExecuted in ScheduleViewBase.

The situation is that I have to update the data in a timer , which will execute update in another thread. Could you please give some suggestion about how to fix it, or some work around? I was trapped for almost a week.

The message of the exception is attached.
Thanks a lot.

I have a custom template for my Appointments , the main problem is Touch events are not working

I  can click or double click in my custom Appointment but  I can not select  the appointments with touch.

Here is my xaml.


My DataTemplate to fill the  content 
 <DataTemplate x:Key="PatientAppointmentDataTemplate">


        <Grid MinHeight="150">
          
<---> Content

        </Grid>


     </DataTemplate>

My Selector.

<selectors:AppointmentSelector x:Key="DefaultAppointmentStyleSelector">
        <selectors:AppointmentSelector.TodayAppointmentSelector>
            <Style TargetType="telerik:AppointmentItem">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="telerik:AppointmentItem">
                            <ContentControl DataContext="{Binding .}">


                                <i:Interaction.Triggers>

///HACK TO FORCE TO SELECT AN APPOINTMENT

                                    <i:EventTrigger EventName="TouchDown" SourceObject="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:AppointmentItem}}}">
                                        <ei:ChangePropertyAction PropertyName="SelectedAppointment"
                                                                 TargetObject="{Binding RelativeSource={RelativeSource FindAncestor,

                                                                 Value="{Binding}" />

                                        <i:InvokeCommandAction Command="telerik:RadScheduleViewCommands.EditAppointment" />
                                    </i:EventTrigger>
                                </i:Interaction.Triggers>

                                <Grid x:Name="Root"
                                      Background="Gray"
                                      Focusable="True">
                                    <Grid.InputBindings>
                                        <MouseBinding Command="telerik:RadScheduleViewCommands.EditAppointment" MouseAction="LeftDoubleClick" />
                                    </Grid.InputBindings>

                                    <ContentPresenter ContentTemplate="{StaticResource PatientAppointmentDataTemplate}" />
                                </Grid>
                            </ContentControl>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </selectors:AppointmentSelector.TodayAppointmentSelector>

My Slots have IsReadOnly= False.

I handled  ShowDialog to personalize the edit or delete appointments.

         this.scheduleView.ShowDialog += scheduleView_ShowDialog;


 private async void scheduleView_ShowDialog(object sender, ShowDialogEventArgs e)
        {
            e.Cancel = true;
           /// My code
        }

But this event does not fire too, when I do double touch simulating MouseDoubleClick.


Please help me. Thank you.

Hello,

I'm trying to display a tree layout with multiple roots - in the sample I attached both "a" and "f" nodes are top level nodes - however only a gets arranged correctly. I was hoping the auto format display something more similar to the image in preferred.png

How does the multiple roots work? is this its intention to specify nodes on the first level? The layout is better if I add a single top level node (called "start" in sample app - you have to uncomment the code), but I don't really want an unnecessary single top node.

Any help would be really appreciated.

Many Thanks

I have a grid with 2 subgrids. This hierachy is defined in the xaml with the ChildTableDefinitions property. The child grids have
in order to avoid a clutter of scrollbars. Also row virtualization has been turned off for as well the main grid as the child grids.

Now I'm implementing a refresh operation. During this, I want to reselect the item that was selected before the refresh was started (there is only one item selected in all these grids). I do this by expanding the appropriate rows until I reach the grid with the item to be selected. Then I set that grid's SelectedItem property.

So far so good. For obvious reasons I want to scroll the selected item back into view. When the selected row was in the main grid, I can just perform a
But when I do this for a childgrid, nothing happens. I presume because the child grid doesn't have a scrollbar and as far as this grid is concerned, the selected row is in view. Also when I try
nothing happens. I guess because objSel is not in the ItemsSource of the main grid (I didn't expect it to work, but I had to try). Also
did not work out.

So I wonder what is a correct approach to scroll the selected item into view.

Thanks in advance,

I've got a FadeTransition set up, with some not too complicated content, which is simply supposed to fade. Instead, it zooms the content in, and then fades. It's like it's taking a snapshot of the old content at the wrong size or something. I can't quite reproduce it outside of the project I'm working on. As soon as the Content is changed, the transition control zooms in on the text, and then fade/zooms it. How do I make this simply a fade, without a zoom?

When you place a transition control in a ViewBox (specifically with the Fade transition, but mostly on all of them), it does a strange scaling.  The text starts out tiny, then goes large, then fades.  In other examples I have done, it starts out almost 2x as large as it should and then fades normally.  Is there a way to stop if from doing this?

See the below code example:

 

Hi,

I'm fairly new to WPF and I'm trying to achieve a look to my datagrids similar to yours from the demo applications.

In your demos, the radgridview(and other controls too like the listview) are wrapped by a telerikQuickstart:Quickstart.ExampleHeader object.

I'm trying to do the same but can't. Can you please point me in the right direction on how I would be able to wrap my datagrid in a similar object, and ideally
change the background color to a deep blue instead of the purple?

Thanks

                   When I close a cofirm radwindow  (showdialog()), it won't focus on a textbox.  If I change it to a regular wpf window and close it, everything is fine.
When I debug it and step through it, it works so it could be some race condition.
