Hello,
An Error message pops up on exiting the application. Here below is the error message.
System.NullReferenceException: Object reference not set to an instance of an object. at Infragistics.Win.UltraWinChart.IGWinTooltip.AddToControlsCollection(Control controlToAttachTo) at Infragistics.Win.UltraWinChart.IGWinTooltip.topLevel_Paint(Object sender, PaintEventArgs e) at System.Windows.Forms.Control.OnPaint(PaintEventArgs e) at System.Windows.Forms.Form.OnPaint(PaintEventArgs e) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer, Boolean disposeEventArgs) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
Any idea on this issue ?
Hi Rivlin,
i have downloaded the service release "NetAdvantage_20081_CLR2X_WIN_SR_2161". Tooltip issue got resolved after upgrading to this service release. Thanq...
Can i get the the latest service release / HotFix for version 8.1?
Can you attach a sample project for me to test this out? I haven't been able to reproduce this otherwise. You can also download the chart's source code and attach it to your application in order to see which instance is throwing the null reference exception, though, you'd have to run the application somewhere with Visual Studio installed.
Hi,
Still am getting the "ToolTip" issue, while working in Windows server 2003 R2 (without having visual studio, i.e.. clean state environment).
Thanks...
