Hello Support
I have used an RadTreeview

It looks like
A
  A.1
  A.2
  A.3
B
  B.1
  B.2

Now while saving the information user has checked on checkboxes for example A.1 & A.2 only
When he revisits the screen I need to show the checkboxes of A.1 & A.2 has checked. How to do this? Tried many of your forums
all the references is pointing towards following line of code.

Please suggest me where I am getting wrong.
Thanks

I have GridView with Radiobutton column, but I don't know how to check/uncheck my radiobuttons programmatically. Could you help me?

 

 

 

 

I like to know how to do it in code once a gridview is binded to a dataset. Can anyone share some examples?

Hello all.

My current EF model looks like this:
Klanten 1----* KlantenOrders *----1 Orders

I have a datatemplate to show all the information on 1 template, looking like this:


I set the CurrentItem to the KlantOrders. Hower, the radgridview does not display the ordersset at all.
When i change the ItemsSource to, for example, the KlantenSet, it does display the tables.
If i set it to KlantenSet.OrdersSet, it also displays the data (but not the data that i need).

So how can i make my radgrid show all the Orders for the selected customer, straight from the Orders table, and not the data form the KlantenOrders table?

I use this code to retrieve the KlantenOrders:


Many thanks, i'm stucked for a long time on this now...

Hi!

Something is happening to me, I appreciate any guide to follow. I have a XBAP main App Full trusted, it added telerik assemblies and my custom assemblies to the references. My custom assemblies referenced has entity classes and general functions and methods which are called from main App and classes (cs file from XAML), and its respective xaml view where to go by using NavigationService.navigate, but something that being taking so long time with no solution is happening to me.

I've constructed a DLL assembly containing XAML views, telerik references and other custom assemblies. Main goal to do it so is because I need to add this Assembly dynamically when is requiered, and that's why this assembly is not added into references into main App. To call a xaml view from main App is by using:

(MainApp)
Assembly dll = Assembly.Load("........dll"); <---- External Assembly not added as reference
object obj = dll.CreateInstance(".../../../mainMenu.xaml");
NavigationService.navigate(obj);

MainMenu.xaml containing telerik components and others is shown successfully, but for some reason when I bind DataContext's MainMenu to my class (ViewModel class) located into my external Custom Assemblies (TransitoMV.dll, and others), system throws an exception:

With telerik assemblies I have no problems, but with mine I do. How can I do to have no problems with TransitoMV.dll and others mine to be referenced by my external dynamic DLL (containing xaml view) assembly?

thanks

Telerik,

I want to show Button(whose content is an image and text) when a RadTileViewItem is maximized and Show only the Image in the button when minimized.  I have created a property which is bind to the Visibility of the button. How can I get the TileState inside this property?

Thanks,

I have some validations that are dependent on other controls.  As an example, let's say I have a textbox where I want the traditional tab off (lost focus) behavior of the textbox to validate ... as well as when a checkbox is selected.  In the checkbox_checked event I can do the following to force an update:

BindingExpression be = tb.GetBindingExpression(TextBox.TextProperty);

be.UpdateSource();

I would like to do something similar with a RadComboBox.  There is a situation where I'd like to force a validation from a different component as well as doing the lost focus of the RadComboBox in question.  I've attempted something similar to the above, but to no avail:

BindingExpression be = rcb.GetBindingExpression(Telerik.Windows.Controls.RadComboBox.TextProperty);
be.UpdateSource();

I've also tried: 

Telerik.Windows.Controls.RadComboBox.SelectedItemProperty

etc.


It appears that no matter what property I try to grab, the returned BindindExpression is always null.  Is there a way to accomplish what I'm trying to do?

I'm using the RadGridview with the Metro theme applied. I want to change, and only change the background color of the HeaderCell. I can do this easily if I'm defining each data column, like below:

XAML:
 <telerik:GridViewDataColumn Header="Type" Width="150" DataMemberBinding="{Binding TypeDisplay}" HeaderCellStyle ="{StaticResource raHeaderCellStyle}"/>

Style:
    <Style x:Key="raGridViewHeaderCellControlTemplate" TargetType="telerik:GridViewHeaderCell">
        <Setter Property="Background" >
            <Setter.Value>
                <SolidColorBrush Color="Blue" />
            </Setter.Value>
        </Setter>
    </Style>

However, if I AutoGenerate columns  I can't figure out how to set this cellheader style. Thanks.

It seems as though the current WPF demo application will not run. I just tried it, it told me there was a new version, it loaded but won't execute. The version is 2011.3.1116.35 I have uninstalled and reinstalled but it always fails.
