Mouse hover over Autohide causes null ref exception

Hi Geoffrey,

I can't seem to duplicate it in our sample project. Can you either give steps that show it there or email over a sample project of your own that shows it?

Hi,

I just sent the project to the support email.

If you load the xml layout ChartLayout.xml and then hover over the left autohide tabs this should reproduce the problem,

Thanks for the demo... it had to do with the tool window having focus before the layout load and then being auto-hidden by the layout. When the auto-hide tab was hovered over, it would raise the exception because the tool window still retained focus and caused some problems internally.

This is now fixed for the next maintenance release. To work around for now, add this line before calling your layout load code: [Modified at 10/23/2006 01:09 PM]

Hi, thanks for the suggested fix and the fast turnaround time!

The suggested fix still manifested the problem (my host container control is the form itself) but I used your suggestion to switch focus to the menu strip which is outside the docking area and that worked.

Here is my load layout code:-

private void loadLayoutToolStripMenuItem_Click(object sender, EventArgs e)
{
//dockManager.HostContainerControl.Focus();
this.menuStrip1.Focus();
// Show the dialog
openFileDialog.Filter = "XML Tool Window Layout Files (*.xml)|*.xml";
openFileDialog.FileName = "TWLayout.xml";
if (openFileDialog.ShowDialog(this) != DialogResult.OK)
return;

// Load the layout
dockManager.LoadToolWindowLayoutFromFile(openFileDialog.FileName);
}
