Hi,

We're using RadDiagram in our application and are trying to use the connector tool to connect two shapes. The shapes have the default connector position ('Auto'), leaving an attachment in the centre of the shape, and we have gliding connectors enabled.

How does the connector attachment behaviour work in RadDiagram? Presumably there's some maximum distance from the target connector that the mouse must be before a connector's IsActive is set to true?

We're finding that, to successfully connect the shapes, we must click, drag and then hold directly over the connector to get the connection to attach properly. What we'd like is to be able to drag the connection anywhere on the shape and it automatically attach to the connector, so long as the connection is dropped on the shape.

Regards,

Ben

I'm using a RadTileList to display a set of tiles from a collection stored in a viewmodel via the RadTileList's ItemSource and ItemTemplate properties. Additionally, I'm allowing multi-tile selection via SelectionMode="Extended".

In my Tile's ItemTemplate, I've defined 3 buttons that access functionality specific to the containing tile. 

I've noticed that clicking directly on any of the buttons contained in a tile toggles the selected state of the containing tile. I'd prefer for a click directly on a contained button to not change the Tile's selected state in any way. So far though, I haven't found any satisfactory way of accomplishing this.

Thanks for you input.

Hello!

My application has a RadTabControl where each tab contains a RadDiagram with a GraphSource-Binding to a view model (TabViewModel).

At the moment I need to reference the RadDiagram in the TabViewModel for loading and saving reasons, because I found no way to save/load a graphsource to/from filesystem.

Having a reference to RadDiagram in my view model is not very MVVM like, make problems in our architecture and is not what we want.

In the end I want to have a single reference to a custom graph source in may TabViewModel which can be loaded by something like graphsource.Load(filepath);

The .Load on the graphsource should populate the graphsource with items and links from the selected file.

The same should be possible for the .Save method.

How could I achieve that?

Thanks.

In MVVM, how to scroll to the previously selected GanttTask when I update whole ObservableCollection gantt tasks?

Hi to all,

I would avoid that user click single item of group.

Sequence to reproduce behaviour:

1. Group more items
2. Unselect group
3. Click on group and group id selected
4. Click again on single item (of group) and selected item is only item that I clicked.

I would that step no. 4 did not have any effect.

To highlight selected items, I have write code into SelectionChanged event, where I change background and foreground of selected item.

Hi, 

I'm working with a RadTreeview binded to an ObservableCollection.

All is fine, until I add a new item in my collection, a new row is created, but the left arrow (to expand) doesn't appear. 

I have to expand with a double click to let it appear. After that all is fine.

Can someone help me ? 

Thanks, 

Benoit.

I am allowing the user to pan & zoom on the graph, for example through the following:

ChartArea.ZoomScrollSettingsX.ScrollMode = ScrollMode.ScrollAndZoom;

At some point, I set the ScrollMode back to ScrollMode.None and want to reset the ranges of the X & Y axes. I want the ranges to be calculated in the fashion they were when the data were originally drawn.

How can I get the ChartView to recalculate the axis ranges?

Please note that I may add data to the chart before triggering the recalc so just remembering range values before pan/zoom and setting them afterwards won't be sufficient.

I would like to be able to modify the list of operators in my field filter. I know I can do it in the way shown here:

http://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/how-to/howto-change-the-default-selected-filter-operator

But if I am creating my own custom GridViewDataColumn or FilterDescriptor class, is it possible to do it from inside one of those two classes, so I don't have to repeat the same event handlers for every RadGridView that I'm using them in?

Hello Telerik Team,

                              I have one problem in my WPF project. I was getting issues when we select more than 6000 documents from radgridview after select these documents i was selecting 1 documents . so it was taking near about 45 seconds time to select the single document. so from telerik team someone suggested to update the telerik versions with the newer one. after upgradation all the radmenuitems were not working and some UI things also not working,i have attached the snapshots of the radmenuitems. what i have to do for it to fix these issues.
