Is there any COMPLETE example to create a custom theme based on Windows7 theme? I tried a lot of ways to do my own reading this forum but no one supports Q1 2012 version; not even WPF. Thank you!

Hello,

When I display a RadCalendar control in a WPF application with the property IsEnabled=false, and then change the property to true. The number days remain grey and when I move the mouse over them they change it Forecolor to black.

<telerik:RadCalendar Grid.Row="1" Grid.Column="0"  Grid.ColumnSpan="2" Grid.RowSpan="2" MinHeight="620" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
		Columns="4" Rows="3" SelectionMode="Multiple" Name="calMain" IsTodayHighlighted="False" AreWeekNumbersVisible="False"
		FontFamily="Segoe UI" HeaderVisibility="Hidden" ViewsHeaderVisibility="Visible"
		IsEnabled="False" Background="White" Foreground="Black" />

private void btnEnabled_Click(object sender, RoutedEventArgs e)
{            
    calMain.IsEnabled = true;
}

How can I avoid this behaviour?

Regards,
Gerardo.

I'm wondering about the reason why RadPane and RadDocumentPane fire the IsVisibleChanged and Unloaded events when I'm just dragging the Pane to an other place on the screen (in my case out of my MainWindow)?

IsVisibleChanged might be plausible, because the Pane becomes invisible for the split of a second, but Unloaded is not plausible, because the the Pane still exists.

So to which event do I have to listen if I want to react on the user clicking on the small cross on the pane to close it, if  IsVisibleChanged and Unloaded happen also when the user is only dragging the Pane?

Hey,

Unfortunately I have a problem in the sort, filter and group functions in the following case:

Class A
{
string AName;
}
Class B : Class A
{
string BName;
}

Class C

{             

A baseClass;

}

 

The item source is ObservableCollection<C>
I am creating in code behind new GridViewDataColum.

If the binding is
1. " baseClass.AName" =>Everything works.
2. " baseClass.BName " =>The grid view rows are ok.All the data is shown in the correct cells,

But the Filter,Group,Sorting is not working.

 

 What can I do?

I have two RadPanes that I wish to persist only the IsPinned property of.  I wish nothing else to be persisted, how would I code this?

The two RadPanes are the only UIElements with a StorageID and their SerializationOptions are set as


When I call Load after persisting, the entire RadDock is missing.

Thank you

We are using Q1 2011  SP1 telerik version. 
There is a radwatermark textbox used in a radgridview. The loaded event is not firing on double clicking the text box in the gridview.
The same functionality works with Telerik version 2010 Q3.
We are not planning to use latest 2012 telerik version due to some animation issues for our application.
Please suggest any quick solution at the earliest.

I am trying to implement a chartview with a line series. The x axis has values in miliseconds. I feel the features of the linear axis suites me more then the DateTimeCategoricalAxis but I can't seem to get it to work with linear axis in both horizontal and vertical directions. Doesn't this work? And if it does, how would I do thìs? Is there any example showing this?    

Hi

i am creating readonly ranges using the InsertReadOnlyRange method.
This works well most of the times.
However I get a NullReferenceException deeply from the tk-lib code
with the following stacktrace:

    
the line raising the exception goes like:


"Parent" is null here.
I noticed that the "null-ness" and the exception only occur if the span is inserted using InsertInline:



so my wish to the telerik developpers is to fix this line of code.
There are circumstances where a spanbox has no Parent layoutbox.
(E.g. when appending it with InsertInline). So you can't use it to get its previous sibling.
If you anaylze the stack trace and the surrounding code of "GetCaretInline"
it's fully OK to null check the Parent property and in this case simply return
the span associated to the layoutbox "currentSpanBox".

Hi,

I am using a TreeListView to display data as multi-column tree. I have set my VM as DataContext to the page and giving my VM property as the ItemsSource of the TreeListView control. When I change the underlying data in VM, it updates the data in the grid normally for the 1st time, but it never updates the data in the grid after that. I checked the data in VM is always right, but the grid never shows the update. It happens only once.

My grid code is:
<telerik:RadTreeListView x:Name="trvHierachyData" ItemsSource="{Binding Path=Data}">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                    <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                        <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                            <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                                </telerik:TreeListViewTableDefinition>
                            </telerik:TreeListViewTableDefinition>
                        </telerik:TreeListViewTableDefinition>
                    </telerik:TreeListViewTableDefinition>
                </telerik:TreeListViewTableDefinition>
            </telerik:RadTreeListView.ChildTableDefinitions>
        </telerik:RadTreeListView>


I am setting the page data context to the VM, i.e. in page ctor - this.DataContext = vmMainControl. The VM has a property by the name of Data which is of type ObservableCollection<T>. The Data collection has Items which is a collection collection of that node.

Please let me know if I am not clear

When the view is initially loaded, the RadPanes start out open, and then immediately shut. This is visible and distracting. I really want them to just be closed from the get go.How can I make it so the RadPanes in a RadPaneGroup are initially closed (unpinned)?
