Hello,

I have a RadDatagrid with more columns and I would like to use sorting functionality by clicking on column headers as it is implemented. Is it possible for some text columns to define own comparer. I need to compare strings "naturally" like: "Ring 1", "Ring 2", Ring 10", "Ring 11",...

Thank you,

Pavel

Hey,

i'm prototyping a WinUI3 App and have a Page with a Grid.
I'm using the RadDataGrid. Now I want to make the columns resizable by the users but the only easy way I found was via the "ResizeHandle" that appears with the setting ColumnResizeHandleDisplayMode="Always".

Is it not possible to just click between Column Headers and resize the columns? Is there a simple solution I'm missing or do I actually have to fiddle around with control templates?

Kind regards,
Christoph

Is it possible to introduce scrollability to the RadDataGrid?

Are WinUI3 Components meant to be responsive to the window dimensions?

I'm evaluating Telerik's UI for WinUI and simply don't have the knowledge nor the time to learn the DataGrid thoroughly.  I have to make a decision between Telerik and a competitor very soon.

The question is about filtering.  I like the filtering in the Telerik grid, with the funnel icon.  However, my client is familiar with a different experience, and prefers it.  Specifically, the client would like a line either between the column headers and the data where the user could simply type and the grid would automatically filter using a "contains" (simple concept, but not so easy for me to describe).  Is that something that could be done with Telerik's grid?  Can it be done with configuration, or would it require custom coding?  Ideally I'd love to see an example (GitHub)?

Thanks in advance.

Hello,

I tried to insert a DropDown button into another one and the inner button is not possible to expand:

            <telerikControls:RadDropDownButton Content="Drop down 1"  
                                   DropDownWidth="180">
                <telerikControls:RadDropDownButton.DropDownContent>
                    <StackPanel Orientation="Vertical">
                        <telerikControls:RadDropDownButton Content="Drop down 2"  
                                   DropDownWidth="180">
                            <telerikControls:RadDropDownButton.DropDownContent>
                                <ListBox>
                                    <ListBoxItem Content="Item 4" />
                                    <ListBoxItem Content="Item 5" />
                                    <ListBoxItem Content="Item 6" />
                                </ListBox>
                            </telerikControls:RadDropDownButton.DropDownContent>
                        </telerikControls:RadDropDownButton>
                        <ListBox>
                            <ListBoxItem Content="Item 1" />
                            <ListBoxItem Content="Item 2" />
                            <ListBoxItem Content="Item 3" />
                        </ListBox>
                    </StackPanel>
                </telerikControls:RadDropDownButton.DropDownContent>
            </telerikControls:RadDropDownButton>

Is it possible to make it work?

I have the datagrid UserEditMode set to "External", and somehow it keeps showing the inline edit mode/box. This happens as soon as I programmatically adda new item to the collection. Is there a way to stop this from happening? I'm looking for a way to hide that blue box and to just programmatically save the changes in the item as soon as any of the cells loses focus:

<telerikGrid:RadDataGrid ItemsSource="{x:Bind ViewModel.Parameters, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" AutoGenerateColumns="False" UserEditMode="External" CanUserChooseColumns="False" UserFilterMode="Disabled" UserGroupMode="Disabled" UserSortMode="None">
    <telerikGrid:RadDataGrid.Columns>
        <telerikGrid:DataGridTextColumn PropertyName="Key" Header="Parameter"/>
        <telerikGrid:DataGridTextColumn PropertyName="Value" Header="Value"/>
        <telerikGrid:DataGridTextColumn PropertyName="Description" Header="Description"/>
    </telerikGrid:RadDataGrid.Columns>
</telerikGrid:RadDataGrid>

using System.Collections.ObjectModel;
using System.ComponentModel;
using CommunityToolkit.Mvvm.ComponentModel;

namespace App1.ViewModels;

public partial class MainViewModel : ObservableObject
{
    [ObservableProperty]
    public string? name;

    [ObservableProperty]
    public ObservableCollection<ParameterViewModel> parameters;

    public MainViewModel()
    {
        Parameters = new ObservableCollection<ParameterViewModel>();
        this.AddNewParameter();
    }    

    private void Parameter_PropertyChanged(object? sender, PropertyChangedEventArgs e)
    {
        var item = sender as ParameterViewModel;
        if (item is not null)
        {
            var index = Parameters.IndexOf(item);
            if (index == Parameters.Count - 1)
                AddNewParameter();
        }
    }

    public void AddNewParameter()
    {
        var Parameter = new ParameterViewModel() { Key = "", Value = "", Description = "" };
        Parameter.PropertyChanged += Parameter_PropertyChanged;
        Parameters.Add(Parameter);
    }
}
public partial class ParameterViewModel : ObservableRecipient
{
    [ObservableProperty]
    public string? key;
    [ObservableProperty]
    public string? value;
    [ObservableProperty]
    public string? description;
}

We use only nested properties in and we whould like to have the same width of name column like group is it somehow possible to do it?

in the picture is group "Expand this group" and property with nested properties "Expand this nested object" where we do not care about value but want to span the columns to one to look similar like group "Expand this group".

Hi Telerik Support Team,

I am encountering an issue with my WinUI project while using the Telerik RadMap control. Specifically, I am receiving the following error:

"Cannot find a Resource With Name/Key RadExpanderStyle."

Hello,

I am encountering a critical issue with the RadMap control in my WinUI application. Specifically, the application crashes after several instances of zooming in and out. The crash happens without any exceptions being thrown or logged, making it difficult to diagnose the root cause.

I would appreciate any guidance or solutions you could provide to help resolve this issue

Below are the details of my setup and the steps to reproduce the issue:

Environment:

• Telerik RadMap Version: 2.10.0
• WinUI Version: WinUI 3
• .NET Version: Net8.0
• Operating System: Windows 11
