Hello,

I am using a RadCartesianChart plotting a CandlestickSeries. When I zoom in i would like to have it more fit. The candles in the screenshot for example are very small and leave a lot of empty space. What would be the best way to make the candles use all of the available space and when you Increase/Decrease the zoom the candles to adjust accordingly. 

Regards

Marko

Hi, 

I would like to bind my itemsource to my view model using FindAncestor but it fails to find my usercontrol.
ItemSource ="{Binding DataContext.ContextMenuItems, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}"

However, by binding like this, without specifying the data context:

ItemSource ="{Binding ContextMenuItems}"

It binds to my view model properly for the first time and does not bind properly when i reopen the context menu and gives me the object type as its header...

Hello.

We are thinking of upgrading from UI for WPF to DevCraft.UI.

The main driver behind this is to migrate our scheduler application.

So my question is: do I have the same features on the ASP.NET.Core scheduler component?

Is there something I will miss in the net.core component, other than the technology gap?

We make good use of: custom appointment, custom edit template, custom slots with special slot style selector, custom resources, paged list implementation of IPagedCollectionView and RadPager, recurrence, drag and drop, as well as custom filtering and ordering,  and so forth.
Is there something I will miss in the net.core component, other than the technology gap?

<telerik:RadWatermarkTextBox x:Name="SearchWatermarkTextBox" Text="{Binding SearchText}"/>
<telerik:RadGridView Name="GridView" behavior:GridFilterBehavior.TextBox="{Binding ElementName=SearchWatermarkTextBox}">

Here is the example code.I can set text in datacontext SearchText property.But when the window opened,I cant see the data without filtered,then the girdview's BusyIndicator has been shown.It looks not good. How to let BusyIndicator be shown when the window opened or let the window opened after data has been filtered?

Thanks

I want to have null as an option in a Combobox, but I can´t figure out how to do that. I´m using MVVM and adds a null value at index 0 to my bounded IList : regioner.Insert(0, null);

Nothing crashes but the user can´t choose the null item.

Best regards / Anna

I use a checkbox PropertyDefinition  which contains NestedProperties,  I want to achieve the checkbox and the expand keep the same status, when the checkbox is checked the nestedProperties expand and when the checkbox is unchecked the nestedProperties unexpand    the code is as follow

                <telerik:PropertyDefinition
                                            Binding="{Binding ​IsShowDetail}"
                                            IsExpanded="{Binding â€‹IsShowDetail}">
                    <telerik:PropertyDefinition.NestedProperties>
                        <telerik:PropertyDefinition Binding="{Binding Path=Name,
                                                                      Mode=TwoWay}"/>
                        <telerik:PropertyDefinition Binding="{Binding Path=Description,
                                                                      Mode=TwoWay}"/>
                    </telerik:PropertyDefinition.NestedProperties>
                </telerik:PropertyDefinition>

 The "IsShowDetail " is a bool property,  the "Binging "and "IsExpanded "both binding to this property

but the "IsExpanded "have no effect

what is the reason for this and how to achieve this effect?

thanks

Hey there,

I have previously used some Tools from Infragistiks. With them I have made a Drag and Drop thing, where I can take Buttons from different Lists on the left side and drop these on buttons on the right side. You can say the right list contains packages and the left side contains parts and now I say these two parts come together in one package.
I now am working to recreate this App with your tools, cause they are simply better. All other parts of the app are done and work, but this drag and drop I dont get to work.

The first problem is, that I don't get the buttons to drag... because of that I made a RadListBox instead of Buttons, but there I have now the problem, that I don't want to add something from the left listbox to the right listbox. It needs to drop into the item on the right side itself. And secondly I have problems with dropping on a button, because I don't have the feeling of a feedback. So the user will wonder, did it drop on the button I wanted it too?

 

I have uploaded a video how it was in the Infragistiks App to wetransfer:

https://we.tl/t-mMG3OKomF1

 

As you can see, there was every list just an ItemControl with Buttons, and only droppable on the right List. And if I hovered over a button, it became darker so it was a direct feedback where I will drop it.

 

I hope I was able to explain my problem, and that someone is able to help me.

 

Greetings
Benedikt
