Hello,

I have a radgridview that is pretty simple. It has 8 columns, all read-only but the last one. The grid holds thousands of records without paging (by design).

The issue I am facing is when the user scrolls to an record that would initially be below the page break and edits the record. When they exit the cell to commit the change the grid jumps back up to the top.

How can I get the radgridview to not jump to the top of records and stay focus on the edited record and surrounding records? Is is an issue with sorting?

Thank you,
Aryn

How to close RadWindow(s) programmaticaly?

I need to close RadWindow(s) which are children of Application.Current.MainWindow programmatically but RadWindows present as "Telerik.Windows.Controls.InternalWindow.ChromelessWindowHelper+WindowHostWindow: Window Header" so I'm unable to cast that back to RadWindow and use Close() method. Here is what I tried:

                foreach (var w in Application.Current.Windows)
                {
                    var rw = w as RadWindow;
                    if (rw == null) continue;
                    rw.Close();
                }

                foreach (var rw in Application.Current.MainWindow.ChildrenOfType<RadWindow>())
                {
                    rw.Close();
                }

So, how exactly do I close RadWindow(s) which are children of Application.Current.MainWindow programmatically?

ContextMenu on DataForm

Hi

We have a problem with ContextMenu in a textbox when we try to use it inside a DataFormDataField, the items doesn't appears, just appear "Copy, Cut, Paste".
We did try populate the ItemsSource property from Opening Event and from a Binding, but doesn´t work
I attached a little example solution

And here some code, the textbox outside DataForm works perfect

<Grid>

<Grid.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="Styles.xaml"/>

</ResourceDictionary.MergedDictionaries>

</ResourceDictionary>

</Grid.Resources>

<telerik:RadDataForm x:Name="DataForm">

<telerik:RadDataForm.ReadOnlyTemplate>

<DataTemplate>

<TextBox x:Name="textBox"

Width="200" ContextMenu="{x:Null}"

VerticalAlignment="Top" Margin="141,125,176,0">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu x:Name="ContextMenuHugo" ItemContainerStyle="{StaticResource MenuItemContainer}" Opening="ContextMenuHugo_OnOpening">

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</TextBox>

</DataTemplate>

</telerik:RadDataForm.ReadOnlyTemplate>

</telerik:RadDataForm>

<TextBox x:Name="textBox"

Width="200" ContextMenu="{x:Null}"

VerticalAlignment="Top" Margin="141,125,176,0">

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu x:Name="ContextMenuHugo" ItemContainerStyle="{StaticResource MenuItemContainer}"

>

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

</TextBox>

</Grid>

Thanks in advance

Cannot upload when embedded in ElementHost

Hello,

I am trying to use the CloudUpload within an ElementHost. When I choose a file and then click upload I get the following error:

Object reference not set to an instance of an object.
at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.UpdateCommandsCanExecute()
at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.SetState(CloudUploadFileState value)
at Telerik.Windows.Cloud.Controls.Upload.CloudUploadFile.StartUpload()
at Telerik.Windows.Cloud.Controls.RadCloudUpload.StartUpload(IEnumerable`1 items)
...

I'm setting up the CloudUpload like so:

var upload = new RadCloudUpload();
upload.Name = "radCloud1";
upload.Provider = new DummyProvider();
elementHost1.Child = upload;

To confirm that I wasn't setting it up incorrectly I tried the same code without the element host and it works fine. Is the ElementHost unsupported?

Binding text in RadGridview footer

I want to put some text in the footer of a column in my gridview. However I can't get the binding to work.

I'm using MVVM. I have one viewmodel for the whole form including the gridview (let's call this MainViewModel) and also one viewmodel per row in the gridview (RowViewModel).

The text I want to show in the footer is in MainViewModel (let's call the property FooterText). How can I bind the text of the footer to this property?

My footer looks like this:

<telerikGridView:GridViewDataColumn.Footer>

<TextBlock Text="Testing" />

</telerikGridView:GridViewDataColumn.Footer>

This example works and displays the text "Testing" in the footer. But my problems starts when I try to set the text using binding instead.

This doesn't work:

<telerikGridView:GridViewDataColumn.Footer>

<TextBlock Text="{Binding Path=FooterText}" />

</telerikGridView:GridViewDataColumn.Footer>

I didn't expect this to work since all other properties of the column gets bound to the RowViewModel and not the MainViewModel. I'm guessing the same goes for the footer.

I've tried this:

<telerikGridView:GridViewDataColumn.Footer>

<TextBlock Text="{Binding ElementName=LayoutRoot, Path=DataContext.FooterText}" />

</telerikGridView:GridViewDataColumn.Footer>

LayoutRoot is the Grid that is the root element of the form that the gridview resides in. This does not work. What confuses me is that I can bind the Header of the column in the exact way and it works:

<telerikGridView:GridViewDataColumn Header="{Binding ElementName=LayoutRoot, Path=DataContext.FooterText}" ... >

I've also tried this:

<telerikGridView:GridViewDataColumn.Footer>

<TextBlock Text=

"{Binding Path=DataContext.FooterText, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=telerikGridView:RadGridView}}"

/>

</telerikGridView:GridViewDataColumn.Footer>

This didn't work neither.

Any more ideas?
