Hi,
We have a problem with gesturing.
We found out that gesturing with the stylus doesn't work properly.
Let us take radcombobox as example. 
Please use the stylus (real stylus which you use on for example Microsoft surface, not this rubbery one)  and the finger only for a test. When you use stylus on radcombobox the list of items drops down but if you selecting item it highlights it but that is it. The highlighted value is not going to the selected text area and the list of items is not collapsing. When you use the finger touch or cursor and mouse it all works. It is just stylus. We have to have stylus to work. The same issue is with other components like for example raddatetimepicker. 
Please help us with this problem.

Thanks,
Grazyna Weimann

1. While in the Week view, click on a slot under Day X.
2. Then click on the header of another day, say Day Y (where Y is different than X).
This will bring you back to the Day view for Day Y
3. Now double-click immediately on any slot to create an appointment. The start time will show the date/time of the slot selected at step 1, not that of the slot you double-clicked on.

Hello,

I have a gridview below. The code "await Task.Run(() => { View.clear(); });" throw an exception:"The calling thread cannot access this object because a different thread owns it." But if I remove "<telerik:GridViewSelectColumn/>", it​ works, please tell me how to fix it? Thanks.

<telerik:RadGridView Name="view" ShowGroupPanel="False" Margin="10" IsReadOnly="True" ItemsSource="{Binding View}" AutoGenerateColumns="False" SelectionMode="Extended">
                <telerik:RadGridView.RowStyle>
                    <Style TargetType="telerik:GridViewRow">
                        <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=OneWayToSource}"/>
                    </Style>
                </telerik:RadGridView.RowStyle>
                <telerik:RadGridView.Columns>
                    <telerik:GridViewSelectColumn/>
                    <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"/>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>

Hello support,

how can I get the selected cell within a TreeListView?

With TreeListView.SelectedItem I get the whole row (mark yellow in attached image), but how can I get the column of the selected cell (see image)?

I need this information to display a summary of the selected column.

 Thanks in advance

Marcus

Hi 

I have the following XAML defining a column with a RadNumericUpDown in the CellEditTemplate

<telerik:GridViewDataColumn DataMemberBinding="{Binding IntegerProperty}" Header="IntegerProperty">
    <telerik:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
            <telerik:RadNumericUpDown ValueFormat="Numeric" Value="{Binding IntegerProperty, Mode=TwoWay}" Minimum="1" Maximum="2" ShowButtons="False" NumberDecimalDigits="0">
            </telerik:RadNumericUpDown>
        </DataTemplate>
    </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

Based on the above XAML, I expect the editor to restrict values to either a 1 or a 2 (these values are just an example). The behaviour I'm experiencing is that when I capture a value outside the min max bounds. The editor does not allow it, but the value displayed by the Grid is the out of bounds value. When I click back on the cell to go to the editor the value is constrained to the bounds. So I'm not sure what the real value is?

Any ideas?

I have a custom QueryProvider implementation, with which I'm able to intercept Linq queries on a custom collection implementation and send this query to an API, implementing server-side filtering of data; I have RadGridViews working this way.

I was trying to achieve this with the RadAutoCompleteBox, while retaining the option to keep free text input, but it seems the ToList of ItemsSource is forcefully called *before* the filtering is done (enforcing client side filtering);

I've looked at the IFilteringBehavior interface, but it seems it gets an IList (which my collection doesn't implement, will ToList be called as well?) as a parameter; is there any way to implement this? I'm going to give IFilteringBehavior a chance, just want to be sure if there's anything better or if it doesn't work.

Hello,

is there a way to place the tabs at the bottom of the document host? Here's my XAML. I'm not sure how to move them to the bottom.

 

Thanks,

Scott

 

<telerikDocking:RadDocking.DocumentHost>
                <telerikDocking:RadSplitContainer  x:Name="gridSplitterContainer">
                    <telerikDocking:RadPaneGroup>
                        <telerikDocking:RadPane  CanFloat="False" Header="Tab 1" CanUserClose="False" CanUserPin="True" x:Name="gridPane">                            
                        </telerikDocking:RadPane>
                        <telerikDocking:RadPane  CanFloat="False" Header="Tab 2" CanUserClose="False" CanUserPin="True" x:Name="gridPane2">                           
                        </telerikDocking:RadPane>
                    </telerikDocking:RadPaneGroup>
