Hi Team,
The Travel Assistant demos are broken... it just hangs. This is also true for the Xamarin Demos, WPF demos and WinForms demos.
Here are some screenshots:

Create an empty project with a RadSpreadsheet. Hide column A and B and try to scroll:

When the CheckBox of a RadTreeNode is checked programmatically, the Unknown Action parameter needs to be passed to the NodeCheckedChanging/ed event.
Copy some content and paste it in the editor. The PasteOptions dialog remains opened and if the user clicks the PrintPreview button an error occurs:

Add a RadTextBox on the form and open its smart tag:
Open the editor for the font and select the entire text:
Then, press Del:
When you try to close the editor, an error occurs:
However, the Font is already serialized as null:
As a result, the designer can't be opened any more:
Just to report a minor typo:
FitlerViewTextCategoryItemCreatedEventArgs, in Telerik.WinControls.UI.FilterView
To reproduce:
private void RadTreeView1_NodeCheckedChanging(object sender, Telerik.WinControls.UI.RadTreeViewCancelEventArgs e)
{
Console.WriteLine(e.Action);
}
The action is always unknown.
To reproduce, use the following code and minimize the child form:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
this.IsMdiContainer = true;
RadForm form = new RadForm();
form.Text = "MDI Child";
form.MdiParent = this;
form.MinimumSize = new Size(800,600);
form.Show();
}
}
The designer tries to load the assembly and throws the following error:
Run the attached project and minimize the form. Then, restore to its normal state:
Initial state:
After minimizing the form and restoring to its normal state, the arrow for RadDropDownList seems clipped:
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
public RadForm1()
{
InitializeComponent();
this.SizeChanged += RadForm1_SizeChanged;
this.timer1.Start();
}
private void RadForm1_SizeChanged(object sender, EventArgs e)
{
this.Text = this.Size.ToString();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.WindowState = FormWindowState.Normal;
}
else
{
this.WindowState = FormWindowState.Minimized;
}
}
}
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?
Open the Demo application >> Interactive Forms example and apply the Office2019Dark theme. You will notice that if the text field enters edit mode, it is difficult to read the input due to black fore color and black backcolor:
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
