Description

A pane that has Closeable="false" set does not render a "close" button and should not be closeable through any user interaction. However, pressing the Esc keyboard key (while the pane is floating and has the focus) closes the pane.

Steps To Reproduce

Run the following REPL example: https://blazorrepl.telerik.com/QTkgmKuM23c0uPv125

  1. Focus the floating pane.
  2. Press the Esc keyboard key.

A slightly different scenario: there are no panes declared in a DockManagerFloatingPanes tag. The user drags a DockManagerContentPane making it float, then presses Esc key: https://blazorrepl.telerik.com/QJuUGUlv43toAJhk40

Actual Behavior

The floating pane closes.

Expected Behavior

The floating pane remains open.

Workaround:
Add the following script to the view:

<script suppress-error="BL9992">
    document.addEventListener(
      "keydown",
      function (e) {
        if (e.key === "Escape" && e.target.classList.contains("k-dock-manager-window")) {
          e.stopImmediatePropagation();
          e.preventDefault();
        }
      },
      true
    );
</script>

Hi Telerik Team,

While working with the DockManager component we encountered a few issues and want to request a minor change:

Inconsistent pane header height
   - When panes are in different states (headers displayed as a Tab vs. as a PaneHeader), their heights differ.  
   - Feature request: please consider introducing size enums (e.g. Small / Medium / Large) so that developers can adjust the header size. At the very least, making the heights consistent by default would help.

Thanks.
Bohdan

When I click and drag content 2 out of the dock, the header gets cleared out.  Panes using the HeaderText property stay put.
    <TelerikDockManager Height="100vh" OnStateChanged="OnStateChanged" OnStateInit="OnStateInit" @ref="dockManager">

The OnPaneResize (and SizeChanged) event does NOT fire when a pane is unpinned. When it flies out from the left, resizing the flyout does not fire events that would letus refresh the chart to fill the new size.

Reproduced in this REPL:  https://blazorrepl.telerik.com/mfkqODwk35srscZe46

Currently, the OnUndock is fired if you just click an item. However, the drag operation hasn't started yet.

I am trying to change the orientation of the SplitPane after the DockManager has rendered but nothing changes. It seems like the parameter is not reactive.

ADMIN EDIT

A possible option for the time being is to dispose and reinitialize the DockManager when you want to change the SplitPane Orientation. 

Here is a runnable sample: https://blazorrepl.telerik.com/QfYHboFl280vuIkL03.
