RadGridView doens't initialize data when using the "Green" theme
If I'm using the green theme, RadGridView will not show the data on the first try.
If I'm reszing my application, searching the data in the radgridview or adding a new item then all the data appears.

When using other themes it's working.

I'm reference this dlls from Binaries folder (R1 2023):

  • Telerik.Windows.Controls.Data
  • Telerik.Windows.Control
  • Telerik.Windows.Control.Docking
  • Telerik.Windows.Control.GridView
  • Telerik.Windows.Control.Input
  • Telerik.Windows.Control.Navigation
  • Telerik.Windows.Data

The class must be in Telerik.Windows.Controls dll as indicate in Class Windows11ThemeSizeHelper - Telerik UI for WPF API Reference Documentation, I reference this dll, but the class is not present :(

Have I forgotten something?
Can you help?

Need to change background color of a row based on a condition
I have a RadGridView control on a screen in my WPF program.  The GridView contains data from up to 3 different tables in my database.  I have implemented an Interface in the ViewModel objects so that the RadGridView can display them all.  (The RadGridViews ItemsSource property is set to an instance of an ObservableCollection of the interface). 

In addition, one of the types, called a Read, can have an array of another of the types, called Alarms.  The RadGridView has a RowDetailsTemplate that is only displayed when the number of rows in the Alarms array is greater than 0.  There is a column in the RadGridView which is of a custom type called CustomGridViewToggleRowDetailsColumn that I wrote.  This column displays the row detail toggle symbol only if the row is a Read and the Alarms array's length is bigger than 2.

All of this is working very well.  Now, however, I need to change the background color of any row that has Alarms associated with it.  Can I use the RowStyle and RowStyleSelector properties to do this?  Just exactly how do I make this happen?

Thanks

Tony

NullReferenceException on RadSpreadSheet

Hello guys,

I'm using the RadSpreadsheet component since 3 months. I dont have any difficulties with it, except since this week I met a very strange behavior. In my context, the RadSpreadsheet is loaded from a csv file deserialization, some calculation are replaced by the numeric values and some cells are read to say if the results is good or not. I have a UserControl which contains only the RadSpreadsheet and RadFormulaBar components, with a dedicated ViewModel.

The fact is that sometimes, during the process, some NullReferenceException are thrown and the process is cut. The StackTrace provides big traces into the Telerik environment.

Example of piece of code generating the error:

        Private Sub SelectCell(cell As String)
            Dim columnNumber As Integer = 0
            Dim rowNumber As Integer = 0

            AerodynamicTableController.ConvertNumbersToExcelCoordinates(cell, columnNumber, rowNumber)

            Dim selection As Selection = Me.sprdSheet.ActiveWorksheetEditor.Selection
            selection.Select(New CellRange(rowNumber, columnNumber, rowNumber, columnNumber))
        End Sub

The StackTrace (the GetValueAsNonArrayConstantExpression method needs expression variable which is null):

For this case, I have cheated using a Try Catch statement and the Thread.Sleep() method, andit seems that this piece of code "cancels" the issue:

            Try
                selection.Select(New CellRange(rowNumber, columnNumber, rowNumber, columnNumber))
            Catch ex As Exception
                Threading.Thread.Sleep(200)
                selection.Select(New CellRange(rowNumber, columnNumber, rowNumber, columnNumber))
            End Try

It's like if the RadSpreadsheet component isn't totally build before I'm using it.

But even using my cheat above, I have another NullReferenceException, but I don't know what's the error source because it's catched by my application CurrentDispatcherUnhandledException event:

The {SF} flag is removed juste after the deserialization. 

The {MF} is replaced by a numeric value during the process.

I understand that this case is very strange and complicated to analyze, but do you have any information about these exceptions? I'm using the 2021.1.222.40 Telerik version. I can't really provide you a sample project because it is too big and too sensitive (business environment).

Many thanks.

Valentin M.

Applied Filter not displaying data after refreshing the data by a service call

Hi Telerik Team,
In my RadGridView I have 100 items, I'm applying filters for 2 columns.
The data is filtered and shows 2 items now.

I'm editing some columns (which are not filtered columns) and saving it.

After save, I'm calling the service to retrieve the 100 items (it means I'm refreshing the data).

The data is retrieved, but the RadGridView displays empty as the applied filter not works correctly.

It should display the same 2 records.

If I try clearing any one filter, it displays records based on 1 applied filter.

Please provide a fix for this. I want the filter to be applied after refreshing also.

Awaiting for your reply.

Thanks and Regards,
Muhammad Azhar Shah

What would be the best way to go about recreating the windows 11 settings panel?

Currently, I am working with RadNavigationView but I feel like I don't need dynamically bound DataContext because each settings tab would be different with various buttons. I tried RadTabControl but it isn't exactly what I'm going for style-wise. If anyone has any ideas please let me know.

Here is what I'm referencing.

Tab Navigation in RadGridView
Hello Telerik Team,

I'm using RadGridView and having 40+ coulmns in it, out of which almost 20 columns are editable.

It means I'm having controls inside CellTemplate to select or to enter the data.

I want to jump to each control on pressing Tab key.

If I set IsTabStop="False" for the RadGridView, then it jumps as expected. But, I'm not able to jump to the hidden columns behind horizontal scrollbar due to column virtualization is enabled and hence it jumps to the next row.

If I disable the column virtualization, it jumps to the hidden column's control, but horizontal scrollbar is not moving correspondingly.

If I remove the IsTabStop property for the RadGridView and by setting TabStopMode="Skip" for the non editable columns, it jumps to the editable columns correctly and the scrollbar is also moving corresponding to the focus. But, it is not directly focusing on the controls inside CellTemplate, instead it focuses on the Cells on pressing Tab key. I need to press one more time to focus on the control.

Is there any possible way to focus on the control instead of Cell, and the scrollbar also moves correspondingly when the virtualization is on.

Please advise.

Note:
When I tried by setting Column Virtualization off, the performance is very poor as it has more number of columns and rows.


Thanks and Regards,
Muhammad Azhar Shah
