RadComboBox ItemsSource Refresh removes selectedValue Binding

Hello,
I have a RadComboBox bound to an ItemsSource that is an ObservableCollection. When that ObserableCollection is changed the RadComboBox SelectedValue is set to -1 instead of the binding in the SelectedValue. The underlying object is not changed and still has the correct value.

Here is my binding.
<telerik:RadComboBox Name="cmbLocation" Margin="0 8 0 0" IsEditable="False" Width="95" ItemsSource="{Binding Lookup.LuLocation}" DisplayMemberPath="LocationDescription" SelectedValuePath="LocationId" SelectedValue="{Binding Path=Line.LocationId, Mode=TwoWay}" HorizontalAlignment="Left" />

How do I keep the binding as the ObservableCollection changes?

Thank you,
Rick

[Solved] RadPane context menu in every child control

Hello,

I have a visual studio like docking layout.
Right clicking on controls that are placed within a RadPane always triggers a context menu that belongs to the RadPane itself ("Movable, Dockable, ..., Hide") and is not the built in context menu of that particular control where the event was triggered from (eg TextBox, FlowDocument, TreeView).

Is there a way to stop this behaviour? I guess it must be something really trivial, I am sorry for that.

Thanks for your kind help.

Marc

Edit: Handling MouseRightButtonUp in the toplevel parent container under RadPane and setting Handled to true will suppress the radpane context menu, but the context menues for any other control like treeviews, textboxes and flowdocuments as well.

[Solved] Is it possible to rebind a GridViewRow without rebinding the complete grid?

Hi,

I am trying to work with RadGridView such that: when data in one (and only) editable column changes, it can change the data in other two or three columns in the same row.

Rebinding the grid in RowEditEnded event works fine, it changes the data in other columns. But the problem is that when I rebind the grid, I lose the keyboard navigation (it means that the column in the next row could not go in edit mode and also, RowEditEnded fires when I just press Tab or Tab+ Shift to move to editable column in the previous row).

My application need to provide most of the keyboard comfort to its users. So, I am looking for a way to rebind the edited row only (when the data in editable column changes and RowEditEnded fires).

Thanks,
Arpit Khandelwal

How to add a event trigger for "PreviewClose" event in a Popup.

Hi!

I have created a popup and from within the popup I have created a telerik docking window. This works fine. But the problem is if the user closes the telerik window by clicking on the "X" then the popup never comes back again. This is because the popup's dependency property IsOpen is left set to true. I want to set up a trigger event so I can hijack the telerik close event so I can first set this property IsOpen to false and then let Telerik to continue the close. Can you please let me know how I can do this? If possible I want to do this from within the XAML file. I figured we can use an event trigger for PreviewClose event and when this event fires then I can set the popup.IsOpen to false. Any help is greatly appreciated.

Thanks,

Sonia

Code for Popup:

<

Popup x:Name="FiberPopUp" Placement="Mouse" IsEnabled="True" IsOpen="False" Focusable="True">

<Popup.RenderTransform>

<ScaleTransform.ScaleX>

</MultiBinding>

</ScaleTransform.ScaleX>

<ScaleTransform.ScaleY>

</MultiBinding>

</ScaleTransform.ScaleY>

</ScaleTransform>

</Popup.RenderTransform>

<telerikDocking:RadPaneGroup>

<telerikDocking:RadPane Header="Fiber PopUp." ContextMenuTemplate="{x:Null}">

</telerikDocking:RadPane>

</telerikDocking:RadPaneGroup>

</StackPanel>

</Popup>

Transform shapes works with state maps, but not the US shapefile??

private void StateLayerReaderReadCompleted(object sender, ReadShapesCompletedEventArgs eventArgs)

{

ScaleTransform scaleMap;

scaleMap = new ScaleTransform(1.2, 1.2);

TranslateTransform moveMap;

moveMap = new TranslateTransform(-50, 0);

TransformGroup tg = new TransformGroup();

tg.Children.Add(moveMap);

tg.Children.Add(scaleMap);

RadMap1.RenderTransform = tg;

if (eventArgs.Error != null)

return;

this.LabelLayer.Items.Clear();

HotSpot hotSpot = new HotSpot();

hotSpot.X = 0.5;

hotSpot.Y = 0.5;

foreach (MapShape shape in this.InformationLayer.Items)

{

string name = (string)shape.ExtendedData.GetValue("STATE_NAME");

TextBlock lblState = new TextBlock();

lblState.Text = name;

lblState.FontFamily = new FontFamily("Trebuchet MS");

lblState.FontSize = 9.5;

lblState.FontWeight = FontWeight.FromOpenTypeWeight(750);

if (

(

name.ToLower().Equals("alaska")

)

{

//ScaleTransform scaleAK;

//scaleAK = new ScaleTransform(-4.5, -4.5);

//TranslateTransform moveAK;

//moveAK = new TranslateTransform(100, -200);

//TransformGroup tgAK = new TransformGroup();

//tgAK.Children.Add(moveAK);

//tgAK.Children.Add(scaleAK);

//shape.RenderTransform = scaleAK;

TranslateTransform moveTransform;

moveTransform = new TranslateTransform(800, 200);

shape.RenderTransform = moveTransform;

}

This worked for me on a map of Pennsylvania (I could move a county shape this way), but not for Alaska and Hawaii on the us ESRI shapefile. I want to scale down Alaska and move is closer so that its visible and scale up Hawaii and move it as well. The transforms seem to not work at all in this case, but, like I said, worked fine on a PA county.
