ToolStripComboBox.DroppedDown

[McPolu]

Hello.

I am trying to set ToolStripComboBox.DroppedDown inside of the Leave
event and it does not work:

public class MyToolStripComboBox : ToolStripComboBox
{
public MyToolStripComboBox()
{
Leave += new EventHandler(ExtendedToolStripComboBox_Leave);
}

protected void MyToolStripComboBox_Leave(object sender,
EventArgs e)
{
if (<SomeCondition>)
{
DroppedDown = true;
}
}
}

The drop down list actually drops down but it is inmediatly rolled up.
I have found the following workaround:

public class MyToolStripComboBox : ToolStripComboBox
{
public MyToolStripComboBox()
{
Leave += new EventHandler(ExtendedToolStripComboBox_Leave);
}

protected void MyToolStripComboBox_Leave(object sender,
EventArgs e)
{
if (<SomeCondition>)
{
Parent.BeginInvoke(new MethodInvoker(SetDroppedDown),
null);
}
}

private void SetDroppedDown()
{
DroppedDown = true;
}
}

And it works. I suppose this is a bug inside the ToolStripComboBox
control. I just want to write about it so if someone finds the same
problem she will find something on the internet. Also, if someone from
Microsoft would like to leave a comment, it will be appreciated.

Thank you.
