Release R3 2022 SP2

Repro-steps

  1. Create a Form
  2. Add a RadGridView control
  3. Add two Text columns
  4. Run the form
  5. Add a new row to the RadGridView with values "a" and "b"
  6. In Excel fill a row with two cells with values "c" and "d"
  7. Select those cells and copy them to the clipboard
  8. In the RadGridView select the first cell of the row
  9. Paste the data

Expected behavior

  • The values "c" and "d" are in the row

Observed behavior

  • The values "System.IO.MemoryStream" and "b" are in the row

Extra info

If the first column is of another type (like GridViewDecimalColumn) a DataError occurs (because "System.IO.MemoryStream" cannot be parces to a decimal).

Searching for a workaround for a previously reported bug, in walked into a little thing:


private void SelectAllCells()
    {
      GridViewRowInfoEnumerator rowInfoEnumerator = new GridViewRowInfoEnumerator((IHierarchicalRow) this.GridViewElement.Template);
      List<GridViewCellInfo> gridViewCellInfoList = new List<GridViewCellInfo>();
      this.MasterTemplate.SelectedCells.BeginUpdate();
      this.MasterTemplate.SelectedCells.Clear();
      while (rowInfoEnumerator.MoveNext())
      {
        GridViewRowInfo current = rowInfoEnumerator.Current;
        if (current.CanBeSelected)
        {
          foreach (GridViewCellInfo cell in current.Cells)
            this.MasterTemplate.SelectedCells.Add(cell);
        }
      }
      this.MasterTemplate.SelectedCells.EndUpdate(true);
    }
The local gridViewCellInfoList is never used and can therefore be removed, improving performance and memory usage in very very very small way.

You could achieve a similar behavior using a custom form. More information can be found in the Add SplashScreen to your application KB article in our documentation.

I am rewriting the RadGridViewPaste-mechanism. Therefor I want to call PastingCellClipboardContent-event using the EventDispatcher.CellClipboardPaste. therefor I need the class GridViewCellValueEventArgs. It has two constructors:

  1. A constructor with indexes. If this one is used, properties RowInfo and Column will always be null.
  2. A constructor which accepts a row and column as parameters. All properties are set and usable.

The second constructor is marked as Internal, not Public. 

Request: Can this constructor be made Public?

1. Set ThemeResolutionService.AllowAnimations = false;

2. Run the attached project and set a filter via the GridFilterButton popup

3. Click "Clear filter" option in the GridFilterButton popup

 

You will see that the GirdFilterButton visual indication is of an applied filter. However, there is no applied filter.

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.

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));
            }

        }

        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

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:

There is a name property in the Property builder properties but it a read only field so the Template names can not be changed. You have to remember what Template 1 is vs Template 2 when referring to them in later use.

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.
