Programmatically position a dockable OverviewControl

[Chris C]

We have an applicaton that uses an OverviewControl and we would like to float the control and position it in a specific location when it is first made visible by the user.

I looked at the SimpleCode sample and tried to something similar but it did not work for the OverviewControl. I modified the DiagramBuilder sample and had a similar problem. Here is the code that I changed in DiagramBuilder MainForm.cs

private void barItemPanZoom_Click(object sender, System.EventArgs e)
{
if(this.barItemPanZoom.Checked == true)
{
// Hide the overview control
this.dockingManager.SetDockVisibility(this.overviewControl1, false);
this.barItemPanZoom.Checked = false;
}
else
{
// Initialize the OverviewControl with the active diagram''s Model & View and display the control
if((this.ActiveDiagram != null) && (this.dockingManager.GetDockVisibility(this.overviewControl1) == false))
{
this.dockingManager.SetDockVisibility(this.overviewControl1, true);
// *** I added this call to FloatControl to position it at the top left of the main form.
this.dockingManager.FloatControl(this.overviewControl1,
new System.Drawing.Rectangle(this.Bounds.Left,this.Bounds.Top,300,300));
this.overviewControl1.Model = this.ActiveDiagram.Model;
this.overviewControl1.View = this.ActiveDiagram.View;
}
this.barItemPanZoom.Checked = true;
}
}

Can you please take a look and tell me what I''m doing wrong? We are currently using 4.1.0.50.

Thanks in advance for your help.

Hi Chris,

I was able to reproduc the situation.You may overcome this behaviour by using the following method.

1.Open the application in Designer view.
2.The Overview control will in floating state.
3.Dock that control to any side.
4.Run the application.And click on the baritem to float the control

Please let me know,if this helped you.

Thank you for the suggestion. However, we would like to float the control programmatically. I found that the FloatControl method works if the control is currently docked. However, I would like to move the control programmatically even if it already floating, and that is not working.

Thanks in advance for your help.

Hi Chris,

You could move FloatingForms using the below method.

if(dockingManager1.IsFloating(overviewControl1)){

FloatingForm ff=overviewControl1.Parent.Parent as FloatingForm;//FloatingForm is a form derived control
ff.Location=new Point(this.Bounds.Left,this.Bounds.Top);
}

Please let me know, if this resolved your issue.
