telerik: containerBindingCollection

[alino]

Hi,

I want to know the equivalent mecanism in WPF to bind Property  of the TreeView and TreeViewItems with properties in the ViewModel using MVVM pattern. For Example in silverlight  I do such and work perfectly:

<telerik:ContainerBindingCollection x:Name="BindingProperties">
   <telerik:ContainerBinding PropertyName="IsLoadOnDemandEnabled" Binding="{Binding Path=Expand, Mode=TwoWay}" />
 <telerik:ContainerBinding PropertyName="IsDropAllowed" Binding="{Binding Path=DropAllowed, Mode=TwoWay}"/>
</telerik:ContainerBindingCollection>

But this one doesn t work in WPF. Can U tell me how to adapt this in the WPF context??

Thank U for your Help

Hi alino,

The ContainerBindingColelction is available only in Silverlight, since in WPF you can bind properties in Style. So in your case you can try this:

<telerik:RadTreeView x:Name="radTreeView" >
    <telerik:RadTreeView.ItemContainerStyle>
        <Style TargetType="telerik:RadTreeViewItem">
            <Setter Property="IsLoadOnDemandEnabled"
                Value="{Binding Path=Expand, Mode=TwoWay}" />
            <Setter Property="IsDropAllowed"
                Value="{Binding Path=DropAllowed, Mode=TwoWay}" />
                </Style>
    </telerik:RadTreeView.ItemContainerStyle>
</telerik:RadTreeView>

Give it a try and let us know if you need more info.

Hi Tina

I am Facing Same Problem

Iam Using  Rad Treeview Custome control it contains style Everthing So  I could not give ItemContainerStyle in Consume Page Once I give ItemContainerStyle That will Affect my own style

Just I drag and drop it

Then Create a Node with Check box but Check box is not Selected

This is our Consume Page Xaml

<local:

TreeView x:Name="RadTreeView1" ToolTip="Enter Name" Height="500" Width="300" ItemsOptionListType="CheckList" IsOptionElementsEnabled="True" > </local:TreeView>

Please help me

Hi senthil,

I am not sure how exactly your local:TreeView control is defined and therefore I cannot be sure what is causing you issue but if the RadTreeView is databound, basically you can bind the CheckState property of the RadTreeViewItem using a StyleBinding, like explained here.

Since the ItemContainerStyle property defines a style for the RadTreeViewItems of a databound RadTreeView, you need to set this proeprty to a style with target type RadTreeViewItem. And if you have already defined such a style, for example RadTreeViewItemStyle, you can set the ItemContainerStyle to: ItemContainerStyle={StaticResource RadTreeViewItemStyle} and modify the RadTreeViewItemStyle to define a binding for the CheckState property of the items.

I hope this info will help you. Let us know if we can further assist you.

I’m working with RadTileView and using RadFluidContentControl to handle three different templates based 
on the TileViewItem state. The solution is C# WPF MVVM Prism. 
I have looked at 279380_Example solution you provided for MVVM which is using Silverlight  
Telerik ContainerBindingCollection  which does not work in WPF.

Is there any sample project that show this functionality in WPF? I’m looking to do something similar 
to the TileView Demo with the flags where in the minimized template I have a short description but 
when a TileViewItem is maximized display a detailed information.

Thank you.

Hi Mike,
Could you please examine the attached project and if you have more questions feel free to ask?

you probably want to update the WPF sample code that you ship with Q3

in FirstLook example.xaml of treeview

        <Style TargetType="telerik:RadTreeViewItem">
            <Setter Property="FontWeight" Value="Normal" />
            <Setter Property="IsExpanded" Value="{Binding IsActive}" />
            <Setter Property="IsSelected" Value="{Binding IsActive}" />
        </Style>

isExpanded and IsSelected are missing - still having the containerBindingCollection in there (the online sample is ok)

Hello Michael,

Thank you for bringing this issue to our attention. We will remove the ContainerBinding definitions from the WPF solution.

I updated your Telerik account for this report.
