I am getting a Target invocation exception while adding multiple series to the Rad Chart.

I have attached a screen shot of the exception.

what is the best method of hiding the HierarchyExpandButton and the column that it adds to the GridView

Hello!
I need in my application the docking feature of the panes - to be able to put them in any position I need in the docking panel, during runtime. But somehow I need to constrain them so there cannot be any floating panel - I mean if the user drags a RadPane but he is not positioning it in any other place, the RadPane will go back to it's initial position.
Setting the CanFloat property on false is just freezing the pane, but I don't want this behavior.

Is this possible?

Thank you!

WPF, VS 2010

I have a treeview bound to a collection of objects that implement INotifyPropertyChanged.  The AssociatedOfferings child collection is a collection of the same type of object.  When I change a value of one of the objects from the ViewModel the change is not reflected in the TreeView.  My View is as follows:


Then in the ViewModel if I take one of the objects and set its IsSelected property to True, or the Name to something else, the change is not reflected in the View.

Hi,
 I have downloaded the beta version of the WPF RadMap specifically to look at the shape file importing.
I have used your examples to render your example .shp files

ThematicLayer.Reader =

 

new MapShapeReader();

 

ThematicLayer.Reader.ReadCompleted += MapShapeReader_ReadCompleted;

ThematicLayer.Reader.Source =

 

new Uri(string.Format(ShapeFilePath, new object[] { layerName, ShapeExtension }), UriKind.Absolute);

 

ThematicLayer.Reader.DataSource =

 

new Uri(string.Format(ShapeFilePath, new object[] { layerName, DbfExtension }), UriKind.Absolute);

 

ThematicLayer.Reader.SourceType =

 

ShapeSourceType.ShapeFile;

 

this works fine, but when I use some shape files that I have bought I get an error when the shapes are drawn on the canvas

  Message=Width and Height must be non-negative.
  Source=WindowsBase
  StackTrace:

If I load my shape files into MapWindowGIS, they require 3 files, the .shp, the .dbf and the .shx.  I can't see where to specify the location of the .shx file in the MapShapeReader?

Am I missing something?

Thanks

Hi,

I would like to know how we can increase the node spacing. Any sample or pointer would be really appreciated.

Hi

When a RadTreeViewItem is selected and the focus is on another element, a black dotted border appears on the focused element.
This looks like the image shown here:
http://blogs.windowsclient.net/anshulee/archive/2008/05/16/removing-the-dotted-border-around-selected-wpf-ui-element.aspx

To remove it using the vanilla WPF elements, I had to use something like this:

<Style TargetType="{x:Type TreeViewItem}"> 
   <Setter Property="FocusVisualStyle" Value="{x:Null}"/>

</Style>

So I tried this with RadTreeViewItem i.e.

<Style TargetType="{x:Type telerik:RadTreeViewItem}"> 
   <Setter Property="FocusVisualStyle" Value="{x:Null}"/>

</Style>

but this does not work. Do you have any workarounds for not showing the dotted border?

Many thanks

I need to convert some cells into GridViewComboBoxColumn only while inserting.  I tried during BeginningEdit event but was unsuccessful.  They need to be readonly during edit.

During AutoGeneratingColumns event they can be converted fine but that causes the column to be a combobox during edit also.  Existing records might have values which are not valid for the combobox.  So, some records do not display existing values.  Also data is generated dynamically so I can't use templates.  Any suggestions?

Hello Telerik Team,

I am currently implementing a WPF RadChart and I am very impressed, but I have one slight problem.

I am using multiple Y-Axis, up to five, and I need the zooming an scrolling feature, as I have to visualize long term data.
I am currently facing two problems:

1) Even when completely zoomed out, I have Scrollbars drawn at each axis, minimzing the screen region for the graph.

2) Every Y-Axis draws a scrollbar. As they all are synchronized anyway, I would like to hide the scrollbards of the additional Y Axis, as this also reduces the graph screen region.

Currently, I am loosing a huge amount of screen real estate to the scrollbars. Is there any way to control the visibility of the bars at each axis? I couldn't find something in the documentation about this.

best regards

Ulrik

I have two gridviews I want to drag and drop rows from one to the other. I cannot get any of the drag event to fire when I select a row and drag with the mouse. The only ones that seem to fire are the DragQuery and DragInfo, neither of which will give me drag effects. All the sample projects provided are for out of date code and need to have a half dozed helper classes. Are there no simple methods to implement this with the new Radgrid?
