I am printing a WPF screen, using the PrintDialog.PrintVisual method. All of the bound controls on the screen print correctly except for the two Telerik controls - RadCartesianChart and RadPieChart. Both of these controls display the message "No data to plot" on the printout.

The data in the controls is bound to the datacontext; and displays correctly in the screen when displayed, the only issue is when printed. Would you expect bound Telerik controls to print correctly?

Thanks.

RadGridView inside Header Binding not set when expander collapsed.

Hi All

I have an issue with binding of a control which is inside header of a RadGridView which is in an Expander where Expander.IsExpanded
=False

<telerik:GridViewDataColumn.Header>

<CheckBox IsChecked="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}"/>

</telerik:GridViewDataColumn.Header>

When I set IsExpanded=True, binding to checkbox starts working as normal.

As a workaround I did this in code behind ..

Private Sub CheckBox_OnLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
            Dim chk As CheckBox = sender
            chk.DataContext = DataContext
            Dim b As Binding = New Binding("MyProperty")
            chk.SetBinding(CheckBox.IsCheckedProperty, b)
End Sub

This works, but I don't want to do this as its not great coding practice and any I will have to repeat this like 1000s time that I don't wanna do..

please tell me what options do I have here.

Thanks
M.

Filtering on Date Only

I've read the documentation that explains how to filter on the Date value only from here:
http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-filter-date-value

But my grid is using auto-generated columns. How do I get this work when I'm not declaring each individual column?

RadPane.RemoveFromParent() exception

RadPane.RemoveFromParent() sometimes throws null reference exception.

It appears that there is a typo in RadPane.cs, RemoveFromParent() method.
In the if statement you should check if this.PaneGroup !=null (with capital 'P').

i.e. instead of:
if (this.paneGroup != null)
{
this.PaneGroup.RemovePane(this);
}

do:
if (this.PaneGroup != null)
{
this.PaneGroup.RemovePane(this);
}

RadPaneGroup ItemTemplateSelector not working

I am attempting to use an ItemTemplateSelectorselector with the RadPaneGroup control.

<telerik:RadPaneGroup x:Name="RadPaneGroupMain" ItemsSource="{Binding OpenDocuments}" ItemTemplateSelector=" {StaticResource OpenDocumentTemplateSelector}">

</telerik:RadPaneGroup>

The ItemTemplateSelector is defined as a static resource on the window. It is getting instantiated (tested via breakpoint in constructor) but the DataTemplateSelector.SelectTemplate method is never called. Code for the DataTemplateSelector is below.

internal class ModuleNodeEntityDataTemplateSelector : DataTemplateSelector

{

public const string NoModuleEntityEditorTemplateKey = "NoModuleEntityEditorTemplate";

public override DataTemplate SelectTemplate(object item, DependencyObject container)

{

var containerTyped = (RadPaneGroup)container;

return (DataTemplate) containerTyped.Resources[NoModuleEntityEditorTemplateKey];

}

Multi select combobox in RadGridview

Hi,

We have the requirement to use multi select combobox as the column in RadGridview and also have detail section below should have the multi select combobox which can be bindable with selected item property (collection). It is going to be twoway bindable.

Selecting the detail section dropdown should reflect the RadGridview selected row column and vise versa.

Please have a look on the attached image which holds the explanation of the same. It will be appreciated, if you can provide the solution with example.

Thanks,

GridView
