Hi

I have created a behavior for quickly adding appointments on mouse up.

I have currently been using the SelectedSlot (Start/End) property of RadScheduleView to create an appointment, but now I discovered that when selecting with Alt-key down you can get the same Start/End selected over multiple days. When debugging I can see these intervals in the Slot.Infos property, but this property is internal so I can't access it.

Is there another way to find these intervals in the RadScheduleView?

Hey i dont want to use the integrated version of the Searchpanel because my design has it a different possition than direktly above it.

So i want to use  <telerik:GridViewSearchPanel   /> but i dont know how to bind it to the RadGridView.

Thanks

Hi,

We have an old application (VB6) that we are migrating to WPF and .NET 8. I use your WPF controls in this application. We use this application to creat test templates for different instruments.
Each test template consists of one or more subtest templates. Each subtest template consists of a test grid with different number of rows and columns, depending of instrument and type of test.
The subtest template grids data is stored in a database. Each subtest are stored in one table, each column number is stored in one table with foreign key to the subtest table, each cells value and row number is stored in one table with foreign key to the column table.  

So far I have managed read data to my gridview with the help of your article https://docs.telerik.com/devtools/wpf/controls/radgridview/how-to/use-mixed-clr-dlr-properties.

First question,
I want the 4 first rows to be comboboxes, different combobox data for each row. I have been able to get comboboxes with DataTempletSelector, DataTemplate and RadGridView_AutoGeneratingColumn,
with help from this forum post from Petar Mladenov https://www.telerik.com/forums/unable-to-use-datatemplates-with-gridview-dynamic-data-not-even-with-icustomtypeprovider.
But my problem is that I don't get any data in the comboboxes. So how should I define my combobox so it databinds to my collection of comboboxdata? 

Second question,
If I manage to fill the comboxes with data I don't know how to databind selectedvalue to my ObservableCollection<MyDataRow>, so how can I do that?
The rest of the gridcells are textboxes and they databinds automatically and updates my ObservableCollection<MyDataRow> when I change a value in a cell.

This is my gridview,

                    <telerik:RadGridView  x:Name="TestCasesGridView"
                                          ItemsSource="{Binding SubtestTestCases, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, BindsDirectlyToSource=True}"

Hello, telerik,

I tried to upgrade my old WPF apps from 2021 R3 to 2023 R3, which was based on .NET 5.0.

When running the upgrade wizrad, it says that no Telerik project found,though there are 45 projects.

OTOH my old WPF apps which has been made on .net 4.6 upgraded to 2023 R3 without problem.

So, I opened C:\Program Files (x86)\Progress\Telerik UI for WPF R3 2023\binaries folder,

but there are every .net version dll folders except .NET 5.0.

Is .NET 5.0 not supported any more or something I forget to read  ?

thanks.

Kang
