I'm using the latest version of the WPF controls and am trying to do a RadGridview->RadGridview drag and drop. Unfortunately, all of the examples I've been able to find seem to be for a much older version of the Telerik tools, and contain references to properties that don't exist in the version I'm using.

Does anyone have a complete example (C#, ideally, but anything will do) that uses the current release of the Telerik controls showing how to drag and drop between two RadGridview controls? Thanks.

RadGridRow MouseLeftButtonUp event is not firing

Hi,

I would like to detect mouse click on each row in RadGridView. Here is my code sample:

private void ContactsGridViewRowLoaded(object sender, RowLoadedEventArgs e)

{

e.Row.MouseLeftButtonUp += delegate(object sender1, MouseButtonEventArgs e1)

{

MessageBox.Show("click!");

};

}

The problem is that this event is never fired. I can change event to MouseRightButtonUp or even MouseEnter and it all works fine. Why i cannot subscribe to MouseLeftButtonUp?

DatamemberBinding and Header

Hello,

I am using the MVVM pattern. I have a GridView on a usercontrol that has the datacontext set to a viewmodel. The viewmodel contains an ObservableCollection of model objects that are bound to the ItemsSource of the GridView. My GridViewDataColumn.Header properties are bound to some properties in the viewmodel and everything works as expected. The Header values are genrated dynamically and dispalyed properly through the binding. When I add a DataMemberBinding to a GridViewDataColumn and bind it to a property from the object collection, I get unexpected Header value. The Header will display the value "SourceName". This only happens when the SourceName property exists on the model object and a successful binding is created for the DataMemberBinding property. If I put in a value such as SourceNameTest, the Header is displayed correctly. Here is a snippet of one of the columns in question. As you can see it is a very simple column definition. Could you please help me understand if there is way to accomplish what I am trying to do.

<telerik:GridViewDataColumn DataMemberBinding="{Binding SourceName}" Header="{Binding SourceObjectHeader}" >
Thanks,

Jason

Using EF 4.0 - can add new row *or* sort

I'm using Entity Framework 4.0 and have a "Players" class. Bone-stock, nothing added or changed, just as VS2010 generated it, which means it's an ObjectSet.

If, in my _Loaded event I do this:

CollectionViewSource myCollectionViewSource = (CollectionViewSource)this.Resources["playersViewSource"];
myCollectionViewSource.Source = this.DbContext.Players;

I can click to add a new row, update existing items, etc. I can't click on row headers to sort them, though.

If I do this:

myCollectionViewSource.Source = this.DbContext.Players.ToList();

then I can sort/and add a new row, but dbContext.SaveChanges() doesn't have any effect.

I'm new to both EF and the RadGridView, so I'm not sure what the problem is. I'd like to be able to both update and sort. How do I do this?

Thanks.

Pin Functionality

Hello,

I was wondering if the WPF GridView has the same pinning functionality as the WinForms gridview documented here: http://www.telerik.com/help/winforms/gridview-rows-pinned-rows.html

I didn't see anything in the WPF samples and the WinForms code doesn't work for WPF.

Thanks,
Derek

How to measure the openstreemap by drawing a polyline

Hi Telerik team,

Thanks for the reply. It's working now.

One final question I have right now, Please respond.

Can we measure the openstreemap means you click on some points and it draws a poly line and during that time it shows the length of that polyline in meters / feet.

Please let me know if it possible or not?

If you have some sort of sample code please pass over it.

Thanks for your help.
Vivek,

How to Set EmptySelectionBoxTemplate in code?

I have a RadRibbonComboBox in a RadRibbonTab in a RadRibbonBar. Looks something like this:

<telerik:RadRibbonBar>

<telerik:RadRibbonTab Header="Tab 2" x:Name="Tab2">

<telerik:RadRibbonGroup Header="Select an item">

<StackPanel Orientation="Vertical" Margin="0,5,0,0">

<telerik:RadRibbonComboBox Name="myComboBox" Margin="0,5,0,0" >

<telerik:RadRibbonComboBoxItem Content="New Item..." Selected="NewItem_Selected"></telerik:RadRibbonComboBoxItem>

</telerik:RadRibbonComboBox>

</StackPanel>

</telerik:RadRibbonGroup>

</telerik:RadRibbonTab>

</telerik:RadRibbonBar>

I have defined three different Data Templates in the resources like this:

<UserControl.Resources>

<DataTemplate x:Key="EmptyTemplate1">

<TextBlock FontStyle="Italic" Text="Select a value from the list" />

</DataTemplate>

<DataTemplate x:Key="EmptyTemplate2">

<TextBlock FontStyle="Italic" Text="There are no selections at this time" />

</DataTemplate>

<DataTemplate x:Key="EmptyTemplate3">

<TextBlock FontStyle="Italic" Text="Please complete the first tab before selecting" />

</DataTemplate>

</UserControl.Resources>

I want to use a specific Data Template for the EmptySelectionBoxTemplate depending on various conditions. Therefore, I want to set the EmptySelectionBoxTemplate in code. I have tried setting the template like this:

myComboBox.EmptySelectionBoxTemplate = (DataTemplate)FindResource("EmptyTemplate1");

The resource is found, and appears to be set in the combo box, but the display does not get altered. I also tried invalidating the property and visual state:

myComboBox.InvalidateProperty(RadComboBox.EmptySelectionBoxTemplateProperty);

myComboBox.InvalidateVisual();

Invalidating did not help. The combo box selection is -1, and if I set the EmptySelectionBoxTemplate in XAML, the box displays the message correctly.

What is the correct way to change this template in code?
