i am using rad gridview  one of the column is Gridviewcombobox column, when i set the ItemContainerStyle of the combobox i am loosing data, when i click the dropdown instead of getting tubelist i am getting the object name. if i comment the ItemContainerStyle its working fine.

Hello,

I have used expression dark theme for a rad grid view, the grid displays same icon for both ascending and descending order when sorted.

 Could you please suggest a solution for this.

I'm trying to change the default colour of the header row on the expression dark theme of the grid view. I've edit a copy of the default style, but no matter what colours I change the background remains the same dark grey. I've managed to find and change the colours of the cells that make up the column headings. However there is a section remaining that isn't a column heading, just empty space on the right of all the column headings. Has anyone had any success in changing this default colour? 

The most obviously thing to change would be the value of the background in 

<SolidColorBrush x:Key="GridView_HeaderRowBackground" Color="#FF2D2E32" />

But this has no affect, even if I make it a bright red just as a test. Even attempting to hard code a value in the border has no effect.

<Border x:Name="PART_GridViewHeaderRowBorder" 
Background="Red"
BorderBrush="{TemplateBinding BorderBrush}" 
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
Padding="{TemplateBinding Padding}"
Grid.ColumnSpan="4" 
BorderThickness="{TemplateBinding BorderThickness}">
</Border>

Hello

I have a WPF Telerik RadGrid View, in which the row should have different colors based on a boolean. i was able to do this with data triggers, but the problem is that i was unable to disable the mouse over and select effects on the row. as a result, even though a particular row has a different color due to the boolean, when the mouse moves over or when the row is selected, it gets selected/mouse over color effect. is tere a way i can disable the mouse over and selected properties for this particular row. Setting the IsSelected and Focusable properties to false also didnt make any difference. The style and data triggers is as follows:

<Style x:Key="RadRowStyle" TargetType="{x:Type telerik:GridViewRow}"> 
            <Style.Triggers> 
                <DataTrigger Binding="{Binding ABC}" Value="True"> 
                <Setter Property="Background" Value="Blue"/> 
                <Setter Property="IsSelected" Value="False"/> 
                <Setter Property="Focusable" Value="False"/> 
                <Setter Property="FocusVisualStyle" Value="{x:Null}"/> 
            </DataTrigger> 
            <DataTrigger Binding="{Binding ABC}" Value="false"> 
                <Setter Property="Background" Value="Transparent"/> 
            </DataTrigger> 
        </Style.Triggers> 
    </Style> 

Hello,

I wan to export data asynchronously. During exporting I want to display progress bar.

Here is the code, with is working, but unfortunatelly not asynchronously - my UI is still freezed. I think it's because of Dispatcher. I have to use dispatcher because grid is created in another thread. So even if I created separated thead function grid.Export() is still invoked by main UI thread.

How I can resolve this problem?

ThreadStart start = delegate()
            {
                grid.Dispatcher.Invoke((EventHandler)delegate(object ss, EventArgs ee)
                {
                    grid.Export(ms);
                }, new object[2]);
            };
            new Thread(start).Start();

Hi,

I have a grid with numeric data that can be edited by the user. If the user enters a non numeric value the edit should be cancelled and the cell value should revert to the original value (skipping validation). When the grid is bound to a DataTable I am able to do this using the CellValidating event as such:

private void OnManualSplitPointsValidating(object sender, GridViewCellValidatingEventArgs e)
        {
            if (Helper.IsNumeric(e.NewValue) == false)
            {
                var grid = (RadGridView) sender;
                grid.CancelEdit();
            }
        }

But when I apply this same code to a CSLA collection the line grid.CancelEdit() causes a row deletion. This may be a problem with the CSLA list but I wanted to check if there is a different way of reverting to the previous value (or if indeed this is supported at all).

I am using the latest Beta and .NET 4.0.

Cheers,
Jose

I'm writing my own custom "export to excel" command for the WPF GridView.  Since I can apply custom styles and want them applied to my exported spreadsheet I need to iterate through all rows / cells and snag not only content but styles.  I can't seem to figure out how to do this (obviously it's set up to allow you to iterate through the underlying data items).  I was thinking about using ChildOfType or something.  Any thoughts?

WPF is all about the user experience. I'm developing a line of business application and need some working examples of a beautiful data entry form.

I'm planning on using a DataGrid and a modal window to add, view and edit records.

Here's an example of a great looking solution for Silverlight, but it's using a Popup control and not a modal window.

(Silverlight example is near bottom of this web page)

Hi there, 

Is it possible to use HierarchicalDataTemplate in RadTreeListView? 
Here is the reason for my question above:

I have object structure as shown below:
1. Class A, it has collection of object of type Class B as one of its properties (in the hierarchy, object of type Class B will be Class A object's children)
2. Class B's has collection of object of type Class A as one of its properties and so on.(in the hierarchy, object of type Class A will be Class B object's children)

I notice that in order to use RadTreeListView, parent and children must be in the same type.
This scenario can be achieved using TreeView with two HierarchicalDataTemplate, but the requirement from customer needs column for each node in the tree view (like what RadTreeListView offers). So I'm thinking if we can use HierarchicalDataTemplate in RadTreeListView than we can solve the problem here.

If RadDocking is docked, how can we force it to be on top of other windows in the application?

When i set RadDocking as dockable, that time the Raddocking go behind the window. But i want to be on top of  any usecontrols.
