Paint issue when serealizing from XML

[Barry Harkness]

When loading the RadDock from a previously saved XML file, there is a noticeable paint issue. The first thing drawn on screen is one of the docked windows, then about a second or two after that, the rest of the dock loads. Simply turning off the loading from XML fixes the issue. I thought it might be a problem with the RadDock's active window being incorrectly set, but after reading this post (http://www.telerik.com/community/forums/winforms/dock/autohide-doesn-t-seem-to-work-for-right-docked-toolwindows.aspx) and explicitly setting the active window, I don't think active window is the issue because the paint problem persists.

Thoughts?

Hi Barry,

Thank you for contacting us.

Most probably this is due to the fact the LoadFromXML method is trying to activate an Auto-hidden window, which on its hand will be animated and thus will block the UI thread for a second.

You may try the following approach:

private void LoadRadDock()
{
    //begin a transaction block
    this.radDock1.BeginTransactionBlock(false);
    this.radDock1.LoadFromXml(@"my\file\path\state.xml");
    //activate a window, that is not auto-hidden
    this.radDock1.ActiveWindow = this.toolWindow1;
    this.radDock1.EndTransactionBlock();
}

Please, let me know whether this is of help.

Best wishes,
Georgi
