HiI am using 8.3.20083.2132 version of UltraGrid, sometimes we get a exceptionSystem.NullReferenceException: Object reference not set to an instance of anobject. at Infragistics.Win.EmbeddableTextBox.OnMouseDown(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button,Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.TextBoxBase.WndProc(Message& m) at System.Windows.Forms.TextBox.WndProc(Message& m) at Infragistics.Win.EmbeddableTextBoxWithUIPermissions.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, IntPtrwparam, IntPtr lparam)while pasting in to a string field which has a regular expression validation put on it.Any Ideas how it can be fixed.
Can you create a small sample project which demonstrates this error? It looks like a bug to me.
Our QA Reported this bug, they have a habit of randomly clicking here and there on the grid. All I've got is this Exception Trace.
They themselves couldn't reproduce the bug, but this makes our product prone to random crashes, which freaks me out.
Is there a way to determine if a bug was a Infragistics Grid Bug, which I can handle in UnHandled Exception Handler and ignore the bug.
I'm afraid there's not much here to go on unless the problem is reproducible. There's no way of knowing what object was null or why.And there's no way to trap the error as far as I can see.
Got the same error randomly from user, can not reproduce either.
