Making the RadButton a WPF Button produces the proper "100%" string (en-US culture). The RadButton produces "1"
This seems to me to be a bug.

Access cells in dynamic radgridview

I have the following scenario

I have an ItemsCollection in which the ItemsSource is bound to an observablecollection of DataTables. These datatables are dynamically generated at runtime.

When the grid is loaded I want to loop through each of the cells and set a tooltip and background color of the cell based on some condition.

How can I do this?

Thanks,

Billy Jacobs

source code build instructions

I just downloaded the source codes for WPF RadControls in order to comply with the document titled "Technical guidelines for protecting Telerik RadControls for Silverlight binaries when redistributed with other applications". However, I can't find the "source code building instructions" that is supposed to have been bundled within the ZIP File. I tried opening the WPF solution directly from VS.NET 2008 but I got several "Project Inaccessible" and other build errors when i tried to rebuild the solution.

please advise.

thanks!

Expression Columns in RadGridView

Hi,
DevEx has a nice feature called Expression columns for their grid with expression editor. One can use the expression editor to create an expression for a column run time.
Is there anything like that available for RadGridView either in Beta or in the current release version?
thanks
Nick

CellValidating-Event not fired with ControlTemplate

Hi,
i have a gridview with checkboxcolumns (set as controltemplates) like this one:
<telerik:GridViewDataColumn x:Name="colReview" Header="Review Needed?" DataMemberBinding="{Binding IsReviewNeeded}">
                                    <telerik:GridViewDataColumn.CellStyle >
                                        <Style TargetType="GridView:GridViewCell">
                                            <Setter Property="Template">
                                                <Setter.Value>
                                                    <ControlTemplate TargetType="GridView:GridViewCell">
                                                        <Border x:Name="PART_CellBorder" Background="{Binding Background, RelativeSource={RelativeSource TemplatedParent}}" BorderThickness="0,0,1,1" BorderBrush="Silver">
                                                            <CheckBox Tag="CheckSecurity#AssayDialogPlates_Review" x:Name="PART_ContentPresenter" Margin="5,0,0,0"
                                                                HorizontalAlignment="Left"
                                                                VerticalAlignment="Center"
                                                                IsChecked="{Binding IsReviewNeeded, Mode=TwoWay}" />
                                                        </Border>
                                                    </ControlTemplate>
                                                </Setter.Value>
                                            </Setter>
                                        </Style>
                                    </telerik:GridViewDataColumn.CellStyle>
                                </telerik:GridViewDataColumn>

Unexpected behavior for nested TabControls

I have created a small application as a prototype of a larger application I need to build to test some of the functionality of nesting one TabControl within another. For the most part, things seems to work very well. However, I am encountering some strange behavior that I have spent days trying to resolve unsuccessfully. Here's a description of my app:

The outer TabControl is bound to an ObservableCollection of product groups, so I have a tab for each group. Selecting any one of these tabs is supposed to display as its content another TabControl which is bound to an ObservableCollection of products that belong to that group. Selecting any one of these tabs is supposed to display product-specific information and allow the user to select from various configuration options that apply to that product using a ComboBox. Up to this point, things seem to work just fine - all bindings seems to be doing what they are supposed to do.

Now, I would like each group tab to keep track of the last selected product on that tab, and each product tab to keep track of the last selected configuration on that tab, so if I change to another group or product tab, then come back to the original tab, the same product is still selected and the selected configuration is also still selected. Each group tab should function this way. So I added a SelectedProduct property to my Group class and bound it to the SelectedItem property of the product TabControl, and added a SelectedConfiguration property to my Product class and bound it to the SelectedItem property of the ComboBox on the product tab.

This is where the unexpected behavior begins. When I run the app, the first group tab is selected, and the first product tab in that group is also selected as expected and desired. However, when I click another group tab, none of the products are selected on that tab (i.e. none of the tabs have the appearance of being selected) although the content of the product tab indicates the first tab is actually selected. If I select another product tab, the correct product information is displayed, but if I select another group tab, then come back to the previous group tab again, the product selection has changed and the selected configuration has been lost.

I'm pretty sure this is all related to the order in which bindings occur and events are raised, but I have not been able to succeed in getting it to work as desired. Maybe what I am trying to accomplish is not possible using only XAML and I need to add more code behind for the SelectionChanged events of the TabControls? Suggestions?

Here is my complete project code combined into a single file and simplified as much as I can. I've wired the SelectionChanged event of each TabControl just to try to see what is happening.

I've attached the images also. They should be placed in the \Resources\Images folder of the project.

Dragging System.Windows.Media.Animation Warning

Hi to all!
just a short post about a warning during a drag action on a treeview node.
During the drag operation i get always:

System.Windows.Media.Animation Warning: 6 : Unable to perform action because the specified Storyboard was never applied to this object for interactive control

I use the RadControls for WPF version 2009 SP3...to replicate the problem just run the demo: Telerik.Windows.Examples.TreeView.DragDrop you provided with the WPF controls and open the output window.

Thanks.
