Hi,

I found this blog post http://www.buildsucceeded.com/post/2009/07/17/WPF-Disabling-a-row-in-a-Grid-based-off-of-a-value-in-the-source.aspx that talks about using style triggers to turn the grid row on/off using binding. I cannot make this to work with my HierarchyChildTemplate control.

<telerik:RadGridView x:Name="DetailsView"

CanUserFreezeColumns="False" CanUserDeleteRows="True" CanUserInsertRows = "True"

SelectionMode="Single" SelectionUnit="FullRow"

AutoGenerateColumns="False" 

ShowInsertRow="True"

ItemsSource="{Binding ReceiptEditRows, Mode=OneWay}" 

SelectedItem="{Binding DataContext.SelectedRowViewModel, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"

ShowGroupPanel="False"

IsReadOnly="False"  IsFilteringAllowed="False">

   <telerik:RadGridView.Resources>

      <Style TargetType="{x:Type telerik:GridViewRow}">

         <Setter Property="IsEnabled" Value="True" />

         <Style.Triggers>

            <DataTrigger Binding="{Binding Path=CanEditChildRow}" Value="True">

               <DataTrigger.Setters>

                  <Setter Property="IsEnabled" Value="True" />

               </DataTrigger.Setters>

            </DataTrigger>

         </Style.Triggers>

      </Style>

   </telerik:RadGridView.Resources>

   <telerik:RadGridView.Columns>

Is this supposed to work?

Hello,

We have a gridview in a usercontrol that we would like to exand to the size of the window.  However, unless you specifiy the size of the Gridview or the Size of the usercontrol the scroll bars will not appear.  Is there a way around this?  Please note we're using a gridview inside of grid where the grid row definition Height definition is set to "*".  Below is the xaml code along with a screenshot.

Hi

I would like to bind the TreeView using HierarchicalDataTemplate:

 

 

 

<HierarchicalDataTemplate x:Key="rufTreeNode" ItemsSource="{DynamicResource Nodes}" DataType="{x:Type TreeRuf:RufTreeNode}">

 

 

 

 

 

</HierarchicalDataTemplate>

 

My question is how I can bind the DefaultImageSrc, ExpandedImageSrc. All I want is just to bind your existing control (ItemTemplate) to my data using HierarchicalDataTemplate. There is an unlimited level of subnodes. Could you provide the xaml for ItemTemplate or just modify my example above?

Kind regards,

Marinko

Hello,

After upgrading to Q1 2011 I am getting this exception from time to time:

Any ideas ?

The RadCarouselPanel control looks more like a coverflow. Can it be modified like a horizontal slideshow?

Hi!
I'm using standard Telerik filtering control.
My question is: How to set filtering in code and make that selection visible in FilterControl.

I tried to set FilterDescriptor in code. It works fine. Grid filters rows but FilterControl does not check exact checkbox.

Thanks!

 

Hi all,

We have an issue with the TreeView, this issue is that when we select the checkbox of the parent, the child checkbox is not being selected. The weird part is that this behaviour only happens the first time when the tree is not expanded yet. If the tree is expanded then the behaviour works as expected.

I debugged on the events and I see that it only comes once in the event, which normally should happen twice. Is this a bug? Or how can I solve this issue?

Here is our TreeView:

Thank you!

I just wanted to create completely custom styled <telerik:OrientedAppointmentItemStyleSelector.HorizontalStyle> items. I've created resources via Expression Blend and all that stuff.

Then I wanted to edit the template like follows - making it bigger and putting additional controls in it.

I can put additional controls in the grid, but it is not getting bigger. The size remains small and the content is cut off. The Height="150" property seems to have no effect. What's going on here?

Let DoubleValue be a wrapper type around a Double, with an attached TypeConverter that knows how to convert from/to Double. And suppose that we have a GridViewDataColumn bound, via DataMemberBinding, to a property of this type. Pasting numeric strings to this column doesn't work, internally generating an InvalidCast exception.

To me this looks like a bug, the column is ignoring the attached type descriptor. It should be doing

Hi,
I am facing an issue while using the telerik treeview in below scenerio.
the images of the expander has to be changed and it has to be dynamically chosen between two images based on the data is binded to it.
when data is binded to the treeview, based on the boolean column, the nodes has to display different images, if this value is true it has to show one image and if it false it has to show another image.
when the node has expanded, then the image of that noted should be rotated version of the image shown earlier (before expanding).
