Currently, adding a standard MS Form also shows the .vb extension. However, adding a RadForm shows only the name which may lead to incorrect name of the form as it is demonstrated in the attached gif file:

In some specific PDF documents, when it is shown in the PdfViewer, the text is missing. This behavior is not observed in the R1 2023 version of our controls. With the R1 2023 SP1 some documents are not visualized correctly.

After revamping the documentation for the Telerik UI for WinForms product, the following problems occurred:

1. Search for a specific class or method in the search box in the following site: https://docs.telerik.com/devtools/winforms/introduction. Select one of the results referring to the API documentation. As a result you will be navigated to the main page of the API reference instead of to the respective class or method. Refer to the Problem1.gif file. It seems that the search results from the API reference return old links for the previous API link pattern.

2. The search box in https://docs.telerik.com/devtools/winforms/api/ is significantly lagging while typing. We should consider performing the search operation after pressing Enter and not with each keystroke. Please refer to the Problem2.gif file.

3.  When you scroll the navigation view on the left side to a certain position and select an article, the vertical scrollbar sometimes gets reset to the top position and you have to scroll back.  (Note that this problem is not reproduced each time).

This exception was caught when deleting the text in the search row letter by letter. Deleting the last letter leads to errors in some cases. Internally in the GridDataCellElement GetSearchHighlightRanges() method, the Text.Length property is used. However, when the Text is null an exception will be raised. So far this exception was not isolated in a sample project. Still, it could be consider adding a null check for the Text property of the cell.

The error message appears when opening the custom option from the filter icon in RadGridView. 

The error message should not appear as there is a text in the textbox. When the enter key is pressed, the textbox value is still not committed which leads to this error. As a workaround, we can create a custom CompositeDataFilterForm override the ProcessCmdKey where we can handle this case.

public class MyCompositeDataFilterForm : CompositeDataFilterForm
{
    protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
    {
        if(keyData == Keys.Enter)
        {
            this.Controls[2] as RadButton).Focus();
             (this.Controls[2] as RadButton).PerformClick();
        }
        return base.ProcessCmdKey(ref msg, keyData);
    }
}

private void RadGridView1_CreateCompositeFilterDialog(object sender, GridViewCreateCompositeFilterDialogEventArgs e)
{
    var newForm = new MyCompositeDataFilterForm();
    e.Dialog = newForm;
}

Here is the error:

To reproduce this error, RadBindingNavigator control needs to be added to the form. Then add a label and try copy/paste it using context menu of the designer. The above error will appear.

So far, using Ctrl+C, Ctrl+V combination for copy/paste does not lead to this error and can be used as a workaround.

It is observable in ControlDefault, Office2010Silver, Office2007Black, Office2007Silver, and Windows7.

Paste some text inside RadRichTextEditor. If the text has more rows than the currently visible area you will see that the control does not scroll down to the caret position.

Workaround:

private void RadRichTextEditor1_CommandExecuted(object sender, CommandExecutedEventArgs e)
{
    if (e.Command is PasteCommand)
    {             
        Application.DoEvents();

        bool cursorAtDocEnd = this.radRichTextEditor1.Document.CaretPosition.IsPositionAtDocumentEnd;
        if (cursorAtDocEnd)
        {
            MoveCaretCommand command = new MoveCaretCommand(this.radRichTextEditor1.RichTextBoxElement);
            command.Execute(MoveCaretDirections.Down);
        }
    }
}
