Hello Team,
We are into the WPF application development. We are using the RadPivotGrid control to view the information grid. To view the same BI format we are saving the view(i.e in XML format). When we save the view. our application is saving the data in our database in XML format. Please review the attached file which is saved in xml format. But we want to know the what is the <ValueTypes> node which is created while saving the view. We want to know what is the version number saved in the file. Is there any relation with .net framework version while generating the XML string?
Below is the XML string.

Hi,
My company is using a RadNumericUpDown control being bound via xml to a viewmodel double value. We don't want the viewmodel's value to change until the numeric control has lost focus, however I haven't found a way to do this. I tried using the UpdateValueEvent="LostFocus" property setting in the xaml, however I notice that the viewmodel's value is still changing every keystroke, as opposed to being changed only when the numeric control has finally lost focus.
When that didn't work, I also tried setting the Value={Binding vmvalue, Mode=TwoWay, UpdateSourceTrigger=LostFocus} but that seemed to cause it to never update.
Am I missing something? Example code below:
And the code behind:
When I run this code in the debugger, if I type in 1.23<Enter> I will see this output:
Val = 1
Val = 1.2
Val = 1.23
This shows the bound value is being changed before the control has lost focus.

Hi,
How can I export a hierarchical grid to Excel so that we don't get security warnings? From GridView documentation and this forum it looks like hierarchical grids can only be exported as HTML or CSV, which doesn't fit our requirements. Could you confirm that it is not possible to export nested grids as xslx? What is the best approach - make custom export all together, or use Telerik API?
Thanks

I am using a RadScheduleView (version 2018.1.116) with the MonthViewDefinition. My users want to be able to select multiple appointments spanning across several months. It appears the RadScheduleView only allows selecting appointments within the current VisibleRange. For instance, if I select a set of appointments in the current month (such as Feb 8-Feb 10), then navigate to another month and hold Ctrl or Shift while selecting another appointment (such as Jan 5), the previously selected appointments are lost, and only the appointment in the visible month remains selected (i.e. only Jan 5 is selected, Feb 8-Feb 10 are no longer selected).
I can select my full appointment range via code-behind (spanning multiple months), but is there a way I can enable this behavior for my users? I assume this would involve a custom AppointmentSelectionBehavior, but looking at the source code it appears the AppointmentSelectionHelper (an internal class) is what's limiting my selection to the VisibleRange.

I have a RadTreeView bound to a collection that contains two types of objects, "Container" and "Item". I use an ItemTemplateSelector to set the correct (Hierarchical)DataTemplate. So far so good, but now I want to style the RadTreeViewItem so I can change selected visual styles and indents and such. I've added an ItemContainerStyle to the RadTreeView, but now the ItemTemplateSelector doesn't work anymore, the RadTreeView is rendered showing type names for all the items.
Is there a way to combine ItemTemplateSelector with an ItemContainerStyle? Should I be using another approach?
My sample code:

I have got an issue when copying to excel from grid using custom Header. The grid has custom headers similar to below
<telerik:GridViewDataColumn x:Name="name1">
<telerik:GridViewDataColumn.Header>
<Grid>
<textBlock text = "header1"/>
...
</Grid>
When the data is pasted into excel it prints the name of the column as Grid ( to string invoked on the header). I tried using CopyingCellClipboardContent event but that only fires for cell values and not for header copying. I wanted to give my custom header names to be copied across to excel. How can i do that?
Thanks

Hello,
Using components from UI for WPF R2 2017 ... It appears that RadGridView column virtualization is causing some binding errors, which in turn seem to place the GridView in a state where column header bindings fail when those columns are not rendered initially due to virtualization. For example, the sample below works if EnableColumnVirtualization is set to false, or if the window size is large enough such that all columns are rendered (such as 800 in the example below).
With the Office2016 theme, I'm getting two types of binding errors:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.RadGridView', AncestorLevel='1''. BindingExpression:Path=DataContext.HeaderText; DataItem=null; target element is 'TextBlock' (Name=''); target property is 'Text' (type 'String')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='Telerik.Windows.Controls.GridView.DataCellsPresenter', AncestorLevel='1''. BindingExpression:Path=Foreground; DataItem=null; target element is 'ContentControl' (Name='PART_ContentPresenter'); target property is 'Foreground' (type 'Brush')
(The sample has a single row in the ItemsSource ... real world situations would produce dozens+ of the errors looking for DataCellsPresenter.)
Other themes I've tested just produce the first binding error.
Here's the .xaml:
<Window x:Class="TelerikWpfApp.MainWindow" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" Title="MainWindow" Height="300" Width="400"> <Grid> <telerik:RadGridView EnableColumnVirtualization="True" AutoGenerateColumns="False" GroupRenderMode="Flat" ItemsSource="{Binding TestObjects}"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}"/> <telerik:GridViewDataColumn Header="Column 1 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn Header="Column 2 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn Header="Column 3 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn Header="Column 4 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn Header="Column 5 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn Header="Column 6 Name" DataMemberBinding="{Binding Column1}"/> <telerik:GridViewDataColumn DataMemberBinding="{Binding Column1}"> <telerik:GridViewDataColumn.Header> <TextBlock Text="{Binding DataContext.HeaderText, RelativeSource={RelativeSource AncestorType={x:Type telerik:RadGridView}}}"/> </telerik:GridViewDataColumn.Header> </telerik:GridViewDataColumn> </telerik:RadGridView.Columns> </telerik:RadGridView> </Grid></Window>
And here's the code:
using System.Collections.Generic;using System.Windows;using Telerik.Windows.Controls;namespace TelerikWpfApp{ public partial class MainWindow : Window { public class TestObject { public string Name { get; set; } public string Column1 { get; set; } } public MainWindow() { StyleManager.ApplicationTheme = new Office2016Theme(); InitializeComponent(); this.DataContext = this; TestObjects = new List<TestObject> { new TestObject { Name = "1", Column1 = "Column1" } }; } public List<TestObject> TestObjects { get; set; } public string HeaderText { get { return "Test"; } } }}
Any assistance would be appreciated.
