Hello,

I'm using a RadDiagram where the users can add images and draw arrows.

By default, when the user draws an arrow over a shape, the arrow connects to the closest connection point. I need to modify this behavior. When the ActiveTool is ConnectorTool and the user clicks on the image, the arrow must start from the point where the user clicked, and not from the closest connection point.

In order to achieve this, I removed all connection points from the image when I add it. This didn't work as expected.

The following code sample allows me te reproduce the error. When I click outside the image, the behavior is nominal.

When I click on the image, an exception is thrown. Instead, I want the application to behave as if the image wasn't there.

In my sample, the ActiveTool is always ConnectorTool, but in my real application, the ActiveTool can have other values. This behavior must only apply to the ConnectorTool. For example, when the PointerTool is active, the user must be able to select and move the image.

I followed the instructions in another post, but I didn't manage to make it work.

I used added the following tool, but the behavior is not what I need. Now, when I click on a shape, nothing happens. I want a new connection to start when I click on a shape.

The post suggested creating a new service or a custom tool, but I couldn't figure it out. In addition, my real application has more styles and custom behavior associated with Connections, so I'd rather not use a different class.

How else can I achieve what I need ? When the user clicks a shape, it must not start from the closest connection, but must instead start from the point where the user clicked.

Hi,

How can clear the "FieldFilter" value?

I have set FilteringMode="FilterRow" on my grid.

Until now I tried:

foreach (var column in gridWithFilters.Columns)
{
    column.ClearFilters();
    column.ColumnFilterDescriptor.Clear();
  column.ColumnFilterDescriptor.FieldFilter.Clear();
}

but this clear the filter, but not its value!

I have also tried:

foreach (var column in gridWithFilters.Columns)
{
    IColumnFilterDescriptor countryFilter = column.ColumnFilterDescriptor;
    countryFilter.SuspendNotifications();
    column.ColumnFilterDescriptor.FieldFilter.Filter1.Value = "";
    column.ColumnFilterDescriptor.FieldFilter.Filter1.Operator = FilterOperator.Contains;
    countryFilter.ResumeNotifications();
}

but I get an error: "Input string was not in a correct format."

Is it possible to clear the "FieldFilter" value?

Thanks!

Hi,

Am writing an application using Radpanelbar . My application has different operation like

PanelBar

*********************************

1) Create

    a.Step1 --> View1.xaml -> screen1

    b. Step2 --> View2.xaml --> screen2

     c. Step3 --> View3.xaml --> screen 3

2) Modify

3) Delete

*************************************

Each operation has various stages (screens/views). When user clicks Create step1  my application should load View1.xaml. 

if he clicks step2 , it should load view2.xaml and so on.

Qn

These Views/viewmodels are already created and stored in Unitycontainer. I just need to load these views when user navigates in the panelbar items.

Can someone help me with this ?

Scheduleview does not fit in available size and it display scrollbars. We want to display scheduleview without horizontal scrollbar.

Please find attached snapshot for same.

Thanks

Hello,
