Please run the attached sample project, open the drop down and press the down arrow key.

Observed: application hangs

Expected: since all menu items in the drop down are disabled, nothing is expected to happen. However, the application shouldn't hangs.

Workaround:

public class CustomRadDropDownButtonElement : RadDropDownButtonElement
{
    protected override Type ThemeEffectiveType
    {
        get
        {
            return typeof(RadDropDownButtonElement);
        }
    }
    protected override RadDropDownButtonPopup CreateDropDown()
    {
        return new CustomDropDown(this);
    }
}

public class CustomDropDown : RadDropDownButtonPopup
{
    public CustomDropDown(RadElement ownerElement) : base(ownerElement)
    {
    }

    protected override void EnsureItemEnabled(RadItem item, bool isUp)
    {
        do
        {
            item = this.GetNextItem(item, !isUp);
            if (item == this.Items.Last())
            {
                break;
            }

        } while (!item.Enabled);
        if (item != null)
        {

            this.SelectItem(item);
        }
    }
}

Release R2 2022 SP1

HI,

 

Exploring the Demo Winforms FilterView component a bug is present.

When you expand several categories ,the automatic Vertical Scroll bar is showed but the "Maximum"  property value is wrong.

You can't see all the items inside. Some items are hidden at bottom.

But if you collapse some category the new "Maximum" values takes the right previous value before collapsing showing more space as expected

I have a workaround to prevent this situation calling CategoryExpandedChanged event.

Firstly I need to call Application.DoEvents() in order to resizing internally by the component all the StackLayoutPanels connaining the Category Items 

After that, I call the private method UpdateScrollBars (Suggested by support) and the ScrollBar takes the right size for its content.

Now I can show all the contained items inside the FilterView panel.

 

FRC

 
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
            DataTable dt = new DataTable();
            for (int i = 0; i < 20; i++)
            {
                dt.Columns.Add("col" + i, typeof(string));
            }
            for (int i = 0; i < 10; i++)
            {
                DataRow r = dt.NewRow();
                foreach (DataColumn col in dt.Columns)
                {
                    r[col.ColumnName] = Guid.NewGuid().ToString();
                }
                dt.Rows.Add(r);
            }
            this.radFilterView1.DataSource = dt;
          
        }


        private void radFilterView1_CategoryCreated(object sender, Telerik.WinControls.UI.FilterView.FilterViewCategoryCreatedEventArgs e)
        {
            e.Category.ExpandedChanged += Category_ExpandedChanged;
            e.Category.Expanded = false;

        }

        private void Category_ExpandedChanged(object? sender, EventArgs e)
        {
            // You need pass the control to Windows main loop to perform the pending telerik events after property Expanded change in order to resize internally
            // the StackLayoutPanel Containers before calling UpdateScrollBars
            Application.DoEvents();
            // Now your code
            MethodInfo mi = typeof(RadFilterViewElement).GetMethod("UpdateScrollbars", BindingFlags.Instance | BindingFlags.NonPublic);
            mi.Invoke(this.radFilterView1.FilterViewElement, new object[] { this.radFilterView1.FilterViewElement.ElementsPanel.Size });
            // Hide the horizontal scrolll bar
            radFilterView1.FilterViewElement.HorizontalScrollBar.Visibility =ElementVisibility.Collapsed;
        }

    }

RadRichTextEditor: Memory leak on importing plain text

Release R2 2022 SP1

Use a custom font set like this: 

this.radSyntaxEditor1.SyntaxEditorElement.EditorFontFamily = new Telerik.WinControls.SyntaxEditor.UI.FontFamily("Cascadia Code");
this.radSyntaxEditor1.SyntaxEditorElement.EditorFontSize = 13;

Then load a large document, at least 10K lines so that the clipping is visible.

The solution in this KB article is used: https://docs.telerik.com/devtools/winforms/knowledge-base/clickonce-application-is-broken 

Follow the steps:

1. Set your main monitor to be with higher than 100% DPI scaling (e.g. 175%, 200%)

2. Set the secondary monitor with 100% DPI scaling.

3. Run the exe from the project on the secondary monitor with 100% DPI scaling. You will notice that all controls that host the standard MS TextBox are incorrectly scaled:

Setting the SyntaxEditorElement.HorizontalScrollBar.Visibility property to Collapsed indeed hides the horizontal scrollbar but it is still measured and arranged and overlaps the view if you shrink the view:

  • I'm using Visual Studio 2022 Community. Running as Admin.
  • I've installed the latest Winforms (Telerik_UI_For_WinForms_2022_1_222_Dev.msi)
  • I open Visual Studio and select to create a Word-like project.
  • The files are all created
  • One nuget reference is present under Dependencies/Packages, but shows as unresolved (UI.for.WinForms.AllControls.Net60 (2022.1.222.0))
  • Using the NuGet Package Manager, there is no Telerik package source present.

So, at this point this seems to be a possible bug. The template project did not setup correctly. I have literally done nothing other than download and install Telerik WinForms today and then try to create this project. This _should_ work or give me instructions of further setup that I have to do manually.

I did try a couple other things, but also failed to get things working.

  • I tried to setup the Telerik Package Source as https://nuget.telerik.com/v3/index.json
  • I was able to see various WinForms packages in the Package Manager, includes the one registered in the project. But VS won't update the project to resolve the package.
  • I uninstalled the nuget package to try reinstalling it, but the re-install failed with the following messages

While working with the Ribbon in a RadRibbonForm, I inadvertently removed a ribbon tab. I started recreating the ribbon tab I removed (and all of the child objects). When I got to creating and naming a ribbon button, it notified me that a control with that name already existed. It appeared that child objects, of the ribbon tab I removed, had not been removed from the form.

I tried to select the existing control from the pull-down on the top of the properties window (to find a way to remove it) and Visual Studio 2022 crashed to desktop. I hadn't saved the form I was working on, so it's mostly messed up in the project (the UI is missing), and I will have to delete what is there and start over.
