Hi Team,

The Travel Assistant demos are broken... it just hangs. This is also true for the Xamarin Demos, WPF demos and WinForms demos.

However, the Font is already serialized as null:

This is reproducible when the ShowGroupedColumns is set to true. In this case, you can sort the group column by clicking on the column header or clicking on the group cell in the group panel. In this case, by clicking the column header, the user can only sort the column in descending mode.

When saving a file with a name that already exists with the RadSaveFileDialog, a message box will appear to confirm the save process. Currently, the control does not provide an option to remove this message box. We can add a property/event to remove this message box like the OverwritePromp property in the MS SaveFileDialog.

This is about this method:

        public void SetError(GridViewCellCancelEventArgs e, Exception exception)
        {
            GridViewDataErrorEventArgs args = new GridViewDataErrorEventArgs(exception, 0, 0, GridViewDataErrorContexts.Commit);
            if (e != null)
            {
                args = new GridViewDataErrorEventArgs(exception, e.ColumnIndex, e.RowIndex, GridViewDataErrorContexts.Commit);
            }
            this.EventDispatcher.RaiseEvent<GridViewDataErrorEventArgs>(EventDispatcher.DataError, this, args);

            if (args.ThrowException)
            {
                throw args.Exception;
            }

            if (args.Cancel)
            {
                //TODO: cancel row edit 
            }
        }

The method GridViewTemplate.SetError accepts a parameter of type GridViewCellCancelEventArgs (named e), but uses the information to create a new object of type GridViewDataErrorEventArgs (named args) and uses information from e to fill args.

The method then fires an event with args. Args also has a property Cancel which can be set in the event handlers. But nothing is done with that property.

Parameter e also has a property Cancel which is never be filled. So it could be useful, at the end of SetError, to set e.Cancel with args.Cancel. This way the caller can use the Cancel information from the events.

This request is also related to my next request. 

PS: Why is GridViewCellCancelEventArgs  called this way? It implies it has arguments for an event, but it is not used for an event, am I right?

In this particular case, we have RadGridView inside RadDock control. The RadGridView is grouped. The ScrollViewer inside the group is trying to load while maximizing the Form. At some point, the ScrollViewer collapsed which leads to re-arranging the items inside the panel and the application hangs.

To reproduce:

1. Create a new .NET 7 project and add a RadForm to it with a single control (e.g. RadButton).

2. Open the designer and have a look at the form's Size.

3. Move the button and save the changes

4. Close the designer and open it again.

Expected result: the RadForm's Size is unchanged

Actual result: the RadForm gets smaller, its height is reduced.

We want to sort a column (the cards in specific Column) in a RadTaskboard. It would be good to have the possibility to use a custom comparer as well
