Hi,

I'm trying to use different GroupHeaderTemplates with Converters for the columns in my grid view.  If I apply the template to the entire grid, my converter gets invoked.

           <telerik:RadGridView.GroupHeaderTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Group.Key, Converter={StaticResource IsActiveConverter}}" />
                </DataTemplate>
            </telerik:RadGridView.GroupHeaderTemplate>

If I apply the GroupHeaderTemplates to GridViewDataColumn, my converter gets called unless the column had a cell template.  My converter gets called for the followiing:

               <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name">

                   <telerik:GridViewDataColumn.GroupHeaderTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding Group.Key, Converter={StaticResource IsActiveConverter}}" />

                        </DataTemplate>
                    </telerik:GridViewDataColumn.GroupHeaderTemplate>

            </telerik:GridViewDataColumn>

My converter (IsActiveConverter) does NOT get called for the following.

               <telerik:GridViewDataColumn Width="16" SortMemberPath="FontFormat">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <Image x:Name="TypeIcon" Width="12" Height="12" Style="{StaticResource TypeIconStyle}" />
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                    <telerik:GridViewDataColumn.GroupHeaderTemplate>
                        <DataTemplate>
                            <Image Source="{Binding Group.Key, Converter={StaticResource IsActiveConverter}}" Height="16" Width="16"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.GroupHeaderTemplate>
                </telerik:GridViewDataColumn>

What am I doing wrong?  Thanks.

 

Hi,

I am binding my observablecollection to CollectionViewSource which has SortDescriptions. On initial load everything loads fine and sorting can be done. 

I have a reset button on which i am trying to refresh the changes in the grid with re fetching observablecollection and binding to ItemSource. Once i do the rebind the sorting doesnot work. 

Below is my collectionviewsource,

Below is the code i am calling on Constructor and also on Reset click,

Hi,

Is there a way to turn off the opacity in the new Fluent theme?

Hello Télérik,

I'm using a RadDesktopAlert in my software.

The declaration :

- Me, and my clients, using 2 or more screens to work. 

- For the moment, i'm using AlertScreenPosition.BottomRight and the notification was displayed in the bottom-right of the main screen (where is the windows task bar), even if the screen software is on a other screen.

I want to know if is it possible to display the notification on the current screen (where is the software, or where is the mouse) ?

Thank you very much, I hope be understadable.

I would like to change the light blue header color of the RadWindow.Confirm. (See attached)

I have asked this question before and got a satisfactory answer, however that answer no longer works. I get a build error that RadWindow is does not exist in the namespace http://schemas.telerik.com/2008/xaml/presentation

Maybe something changed since I asked this question in 2015.

My current project is using the NoXaml binaries.

I'm using the combobox in this example inside a grid as a celledittemplate:
<telerik:GridViewDataColumn Header="َArticle Description" Width="100"><telerik:GridViewDataColumn.CellTemplate><DataTemplate><TextBlock Text="{Binding DataContext.AccDocumentItem.Description1, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"/></DataTemplate></telerik:GridViewDataColumn.CellTemplate><telerik:GridViewDataColumn.CellEditTemplate><DataTemplate><telerik:RadComboBox IsEditable="True" DisplayMemberPath="SLStandardDescriptionTitle"ItemsSource="{Binding DataContext.AccDocumentItem.SelectedSL.SLStandardDescriptions, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"Text="{Binding DataContext.AccDocumentItem.Description1,Mode=TwoWay,RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"><i:Interaction.Triggers><i:EventTrigger EventName="DropDownOpened"><i:InvokeCommandAction Command="{Binding DataContext.SLStandardDescriptionsDropDownOpenedCommand, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}" CommandParameter="DLType2"/></i:EventTrigger></i:Interaction.Triggers></telerik:RadComboBox></DataTemplate></telerik:GridViewDataColumn.CellEditTemplate> </telerik:GridViewDataColumn>

I need to present a grid where one column is a combobox. The user can select one value from the list or enter a new value, the problem is that selected row is repeated in all rows. Can you please tell me what I'm doing wrong?
Your time much appreciated!

Hi every body...

In my application I have to make an InlineUIContainer (inserted within a table) as ReadOnly. To achieve this requirement I tried ReadOnlyRangeStart and ReadOnlyRangeEnd (as shown in the attached code). I also tried to InsertReadOnlyRange around the table using DocumentPosition (not shown in the attached code).  In both cases the following error is thrown:

"An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll"

Is not possible to make InlineUIContainer as ReadOnly? If so; is there any workaround?

Any Help Will Be Greatly Appreciated...

Note: the cause why I used TextBlocks instead of just adding new span to the paragraph; is that I have to make Text and image tightly grouped together; so that if they come across end of the page (and there is no enough space to them), then they move together to a new page. If there is a better solution to this requirement, it will be welcomed.
