When I add an ultrachart to my form, all seems well until I attempt to reopen the designer for that form, then I get the wonderfully useful error.
Collection is read only.
here is the call stack:
at System.Windows.Forms.WindowsFormsUtils.TypedControlCollection.Add(Control value)at Infragistics.Win.UltraWinChart.IGWinTooltip.AddToControlsCollection(Control controlToAttachTo)at Infragistics.Win.UltraWinChart.IGWinTooltip.Attach(Control chartControl)at Infragistics.Win.UltraWinChart.UltraChart.OnLoad(EventArgs e)at System.Windows.Forms.UserControl.OnCreateControl()at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible)at System.Windows.Forms.Control.CreateControl()at System.Windows.Forms.Control.ControlCollection.Add(Control value)at System.Windows.Forms.Design.ControlDesigner.DesignerControlCollection.Add(Control c)
and the line that warning shows up on is misleading.
this.splitContainer1.Panel1.Controls.Add(this.ultraTabControl1);
The form is like this. A splittercontainer where the top pane is holding a ultraTabControl and on the second tab is the ultrachart.
The program compiles and runs but since this is a complicated form, the constant "Ignore and continue" everytime I open the designer is very annoying.
Can anyone tell me how to get rid of this?

i think this is fixed in the latest service release. check this thread for more information: http://community.infragistics.com/forums/t/20891.aspx?PageIndex=1
although the error messages are the same, i believe the fix that was made will resolve the problem for you as well.
Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4
This is really aggravating. I applied the service pack, deleted the tab control (and all the controls with it…<sigh>) re-added it and attempted to drop a grid on it. The grid doesn’t show up on the tab but instead at the bottom of the screen, meaning that I can’t launch the design wizard or do anything else.
Actually, I can’t drag a grid onto anything. So it’s not the tab control, but instead grid…I would guess.
I can drag other controls onto the ultratabcontrol
If I look at the “About UltraGrid” it shows Version 9.1.20091.1000
But when I hover over the UltraGrid in the toolbox, it shows version 9.1.20091.2023
Please help since I’m dead in the water.
Well, I think I'm better now.
I loaded the project into notepad and changed all the references to be 2023 instead of 1000. This gave me all sort of other Tab Control errors, so I then deleted all the tab controls, 'cleaned' the project, exited Visual Studio to clear the cache.
anyway, it seems to be better now.
Sorry for the rant
