Hello,
I am trying to switch an RadTreeViewItem to EditMode on mouse double click.
When I do that, the content of the textbox is empty, isn't it a bug?
Thanks

Hi,
In my project, I can't set all data in ItemsSource.
I want when user filter, I set data to ItemsSource(note: I don't want Telerik to filter current data).

I handle the Filtered event and I set My data to ItemsSource in this function. but Telerik filters new data again.
What am I do to force Telerik don't filtering data by itself?
thanks.

Hi,

I want to be able to redefine the default style of the RadDatePicker to make it look like the rest of our components.

To do so, I put a RadDatePicker in my application, I clicked on it via the 'Document Outline' and chose Edit template -> Edit a copy. I then noticed that the RadDatePicker was now experiencing an issue when I "zoom out" to the "Decade" view : If I click on the left arrow (-10 years) or the right arrow (+10 years), the header text correctly changes (2000 -> 1990 / 2000 -> 2010) but the displayed years in the "calendar" section of the date picker aren't affected by the change. I get the same problems if you zoom out to the "hundred years" view.

Here is the simplest project I could put together to show the issue : https://drive.google.com/open?id=1d_GcDKeUfdmifYbo6KedukOIKtyHSiVo

Here are some screenshots of the problem : https://drive.google.com/open?id=182PK161CCZc_1k4m9rogxl_lSXIF8Lc1

Here are the repro steps :

1. Create a new project

2. Add 2 RadDatePicker

3. Select one of the two RadDatePicker, Edit template -> Edit a copy

4. Notice described issue

I hope this is enough for you to help me with this issue, I guess it must be something missing in the copied style that breaks this mecanism.

Thank you for your time :)

Louis

Hi,

I'm trying to to accomplish the following: whenever a user right clicks whatever data grid, the same context menu should appear.  One of the options in the context menu is the export to Excel.  I'm trying to achieve this by creating a style for the RadGridView.  Here's my xaml:

<Style x:Key="TelerikGridViewContextMenuStyle" TargetType="{x:Type telerik:RadGridView}">
    <Setter Property="ContextMenu">
        <Setter.Value>
            <ContextMenu>
                <MenuItem Header="{bx:LocalizeBinding ExportToExcel, Global=True}" Command="{Binding ExportToExcelCmd}" CommandParameter="{Binding RelativeSource={RelativeSource Mode=FindAncestor,  AncestorType={x:Type telerik:RadGridView}}}">
                    <MenuItem.Icon>
                        <Image Source="/Resources/Icons/Excel.png" />
                    </MenuItem.Icon>
                </MenuItem>
            </ContextMenu>
        </Setter.Value>
    </Setter>
</Style>

As you can see, I'm trying to pass the RadGridView as a parameter to the command.  However, in my code, this parameter is always null.  How come ?

By the document, we can bind the pager as below.

<Grid x:Name="LayoutRoot"
        Background="White">   
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
    <telerik:RadGridView x:Name="radGridView"
                         ItemsSource="{Binding Employees}"
                         AutoGenerateColumns="False">
        <telerik:RadGridView.Columns>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" />
            <telerik:GridViewDataColumn DataMemberBinding="{Binding CompanyName}" />
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Title}" />
        </telerik:RadGridView.Columns>
    </telerik:RadGridView>
    <telerik:RadDataPager x:Name="radDataPager"
                          Source="{Binding Items, ElementName=radGridView}"
                          PageSize="5" />

The question is that I can't assign the element name of the RadGridView. So how to bind the element?

Thanks.

I'm trying to create a custom AggregateFunction that applies different calculations based on the Field that represents the leaf level in the Pivot Grid. It is for a pivot grid that displays revenue for books sold in a library that includes the sum of sold books - a commision difference (the scenario is made up).

View 1:

Selected fields: Library, Categoy, Book

Should display

                        Day 1  
Library              1050
   Fantasy          240 (600-10%)
      Book A        100  
      Book B        200  
      Book C        300  
   Drama            810 (900-10%)
      Book D        400  
      Book E        500

 

View 2:

Selected fields: Library, Categoy
Should display
                        Day 1  
Library              1050
   Fantasy          240 (600-10%)
   Drama            810 (900-10%)

 

In the scenarios above, the -10% needs to be aggregated only on Category level and above, not on Book level. I created a custom aggregate function but wasn't able to find a solution of checking the field that the row to which the aggregate applies belongs to, whether it is Book or Category.

 

Does anybody know how to do this?

Thanks!

I use data binding to set the Min and Max properties for a RadialScale GaugeRange. In the prior version I had (Q1 2013), the data binding worked fine and the ranges displayed correctly, but in 2013.2.724.40 (Q2 2013) I find that the ranges do not show at all if their Min and Max values are data bound. They show fine if the values are hard coded.
I have a TextBlock in the RadialScale.CustomItems collection bound to the same member of the same data object, and that is showing correctly so I know the DataContext is right and the value exists.

Has the handling of Min/Max binding in 2013.2.724.40 changed? Should I use a different property?

                        Command="{Binding FloatPanesCommand}" />
        </telerik:RadDocking.InputBindings>

 

But this does not work and the command is never triggered. Could someone please help.
