Hi Team,

We have prepared a sample for DeferRefresh issue. While creating a Appointment, changing the currentdate(View Refresh) for scheduler, it is thrown "Deferrefresh is not allowed during an addnew or edit item transaction" exception. 

In our application, we have refresh the scheduler view (Changing current date) continuously through bindable property and immediately creating the appointment. Here we are getting this exception.

Sample : https://drive.google.com/file/d/1IL_fqyugJDj2VMX7lqxGXbro1rtRU7sM/view?usp=sharing

Please suggest how to handle this issue?

Thanks,
Srinivasan

Hi 

    I am working on a DragAndDrop about RadTreeListView.There are two screens that use this RadTreeListView, one that requires the draganddrop function, and one that needs to disable the draganddrop function.The screen with the drag function disabled sets the following property to false:

RadTreeListViewDropBehavior.IsEnabled="{Binding CanDragFlag}".But, When this screen is dragged, the content set in DragVisual Content will be displayed. What is going on? I don't want to have any drag effects

Hello,

If the RadSyntax editor is in read-only mode and you press Ctr+F, the find/replace dialog is displayed. If I enter text in Find and Replace and press the Replace button, the text is replaced!

The Replace and Replace All buttons must be disabled in read-only mode.

Hello,

Or at least provide a way for developpers to define a new syntax highlighter.

Hi there,

 

Is there anyway to get rid of time and just show date (ex: 10/08/2019) in Start and End columns? I don't need to see time, I just want to see date.

Please assist me.

 

 

Thanks,

Bahram Afsharipoor

Hi there,

 

I have a requirement which is implementing a horizontally infinite scrolling on a GridView. Basically, I want to be able to add new columns to my GridView and see them as I am end of scrolling(either side). I know how to add and bind new columns to my GridView at run-time, but I don't know if there is any event or trick that I can use to detect if I am end of scrolling or not(so I can add new columns...).

Can someone please help me with this?

 

 

Thanks,

Bahram Afsharipoor

Hello,

The API Reference documentation doesn't have any information about SyntaxEditor...

Hi Telerik,

 

I'm using the following RadTreeListView :

<telerik:RadTreeListView AutoGenerateColumns="False" ItemsSource="{Binding SelectionDetails}" CanUserResizeRows="True" CanUserDeleteRows="False" CanUserReorderColumns="True"ReorderColumnsMode="ReorderColumns" VerticalAlignment="Stretch" ColumnWidth="Auto" GroupRenderMode="Flat" GridLinesVisibility="Both" SelectionMode="Multiple" SelectionUnit="FullRow" FontSize="{StaticResource FontSizeText}" IsReadOnly="{Binding IsReadOnlyMode}" x:Name="rtlvDetails"
                                 AutoExpandItems="True" ValidatesOnDataErrors="InViewMode" ValidationType="None"
                                 SelectionChanged="rtlvDetails_SelectionChanged" EditTriggers="Default" ClipboardPasteMode="AllSelectedCells"
                                 CanUserSelect="False" FrozenColumnCount="3" CellValidating="rtlvDetails_CellValidating" Grid.Row="1" CanUserFreezeColumns="False" IsSynchronizedWithCurrentItem="False"/>

 

I try to implement the copy (from Excel) / paste (to the grid) like I've implemented in another RadGridView :

<telerik:RadGridView Margin="5" HorizontalAlignment="Stretch" AutoGenerateColumns="False" ShowGroupPanel="False" RowIndicatorVisibility="Collapsed"
                                         CanUserFreezeColumns="False" CanUserReorderColumns="False" ItemsSource="{Binding LocalGapTolerances}" IsFilteringAllowed="True"
                                         x:Name="rgvTolerances" Style="{StaticResource StyleRadGridView}" HeaderRowStyle="{StaticResource StyleHeaderRowRadGridView}" SelectionMode="Single"
                                         SelectionUnit="Cell" ClipboardPasteMode="AllSelectedCells" Grid.Row="1" VerticalAlignment="Stretch"/>

 

But what ever I do about the paste mode properties, the 'Ctrl+V' will never fires any event in my RadTreeListView.

I need to paste data from Excel in my grid respectings the Columns/Rows order.

 

Do you know why no event are fired ?

 

Thank you.

Valentin
