I'm glad the FocusVisualStyle has been fixed for the header controls but the docking control is still displaying an erratic dotted rectangle.
We need to ship and can't wait anymore for next upgrade so I need a workaround to remove the FocusVisual rectangle that bounce all around when dragging a docking window.

See image of the problem :

Setting FocusVisualStyle property of the docking control doesn't remove the rectangle. All WPF standard controls and the one I have from different vendors supports the API correctly and I need to make this work for your controls as well. I've read somewhere on the forum that a control template could be used as a workaround but I don't have Microsoft Blend and I don't know how and what to override in the template (I don't know anything about control templates).

Can you provide the template code or whatever that will fix this?

Thanks,
Yury

Cell Validation

Hello,
Is there a way to automatically display the ErrorMessage when validating data on a cell level? So the user does not have to hover over the corner of the cell to see the error message.

Thank You,
Nate

Updating GridView as ObservableCollection is Built

Hello,

We're working on a project to pull data from servers. The code goes over the network to each server of interest and retrieves some server information (i.e. name, Operating System, etc.) which in turn is added to the ObservableCollection. Everything works fine; however, it can take several minutes to go to each server and pull back the data. Therefore, we would like to populate the gridview as the data is returned. For example...application retrieves the name of server 1, the gridview displays server 1 data while in the background server 2 data is retrieved and displayed once it returns, etc.

So here is what we've tried with Gridview bound to an ObservableCollection.

Retrieving the data with a backgroundworker (which works, but the data still does not display on the grid as retrieved).
Tried other Data Types (DataSet, List, etc.) - they all work but all of the data has to be retrieved before being displayed.
Looked at the OnCollectionChanged event and as each server is queried and populated into the ObservableCollection - the event it fired.
Tried changing the DataLoadMode to Asynchronous

Below is the code behind...

ScrollBar with windows default style

Hello,

I'm using the telerik TreeView, which uses the default telerik style for the scrollbar. The other scrollbars in the application have the default windows style. How can I apply the default windows style to the telerik scrollbar?

[Solved] Title for a Grid

Hi,

Not sure where's the best place to post this.

We're looking to create a title for a grid that looks like a docking pane's title - that is, using the Outlook 2007 blue theme you get a light blue background and a navy-ish font color. We're looking for something that is themed the same so if we ever change the theme this will change as well.

Any idea how to do this?

Thanks,
yonadav

GridViewDataColumn with XAML-Image

Hello

I'm trying to do the following in my c# code:

                                Binding binding = new Binding();         
                        binding.Path = new PropertyPath("Image");         
                        binding.Mode = BindingMode.OneWay;         
                     
                        GridViewDataColumn imgCol = new GridViewDataColumn();         
                        DataTemplate dataTempl = new DataTemplate();         
                        FrameworkElementFactory rectElement = new FrameworkElementFactory(typeof(Rectangle));         
                        rectElement.SetBinding(Rectangle.FillProperty, binding);         
                        rectElement.SetValue(Rectangle.WidthProperty, 16.0);         
                        rectElement.SetValue(Rectangle.HeightProperty, 16.0);         
                        dataTempl.VisualTree = rectElement;         
                        imgCol.CellTemplate = dataTempl;         
                     
                        forGrid.Columns.Insert(0, imgCol);         

Every Row-Object has an "Image"-property which contains a XAML-Vectorgraphic. My target is to create a column for the rowobject which shows the image. I was able to do this with the WPF-Toolkit-DataGrid and was wondering how it would work with the RadGridView.

Any suggestions?

Thank you

How change the left icon on RadWindow.Alert

Hi,

I need to be able to change the left icon in a WPF RadWindow.Alert window. From what I understand this can only be achieved via a theme. Do you have a sample WPF VS2008 or VS2010 project demonstrating this ability?

Thanks heaps.

Grouped Grids at Design Time, dont show grouped footer data

Hi All

I have created a grid based on the examples where the GroupFooterTemplate is used to show sums etc in the footer of each group.

This works fine if I group at runtime, but if I specify the groups at design time, this binding does not seem to be piking up the grouped totals and nothing is show in the GroupFooterTemplate sections.

I need to be able to configure design time grouping as it is crucial to our application.

Please find the xaml I am using below:

    
            <grid:RadGridView x:Name="radGridViewRaw1" ItemsSource="{Binding collectionRaw}" Margin="0" ShowColumnFooters="True" ShowGroupFooters="True"

                                    <grid:RadGridView.GroupDescriptors> 
        
                                        <data:GroupDescriptor Member="PressType" /> 
        
                                        <data:GroupDescriptor Member="ProcessWeek" /> 
        
                                    </grid:RadGridView.GroupDescriptors> 
        
                                    <grid:RadGridView.Columns> 
        
                                        <grid:GridViewDataColumn Header="Press Type" DataMemberBinding="{Binding PressType}" /> 
        
                                        <grid:GridViewDataColumn Header="Week" DataMemberBinding="{Binding ProcessWeek}" /> 
        
                                        <grid:GridViewDataColumn Width="200" Header="Copies Printed" TextAlignment="Right" DataMemberBinding="{Binding CopiesActual}" DataFormatString="{}{0:c}">
