WeakReference exception when disposing GridDataBoundGrid

Form.Dispose(bool) method fails with the exception (stak trace is below). I am using Essential Grid version 2.0.3.0 catched at Syncfusion.Windows.Forms.Grid.GridTextBoxControl.WndProc(Message& msg) System.InvalidOperationException: Handle is not initialized. at System.WeakReference.get_IsAlive() at Syncfusion.Windows.Forms.Grid.GridFontInfo.get_GdipFont() at Syncfusion.Windows.Forms.Grid.GridStyleInfo.get_GdipFont() at Syncfusion.Windows.Forms.Grid.GridStyleInfo.get_GdipFont() at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.get_Font() at System.Windows.Forms.Control.GetParentFont() at System.Windows.Forms.Control.get_Font() at System.Windows.Forms.RichTextBox.get_Font() at System.Windows.Forms.Control.AssignParent(Control value) at System.Windows.Forms.ControlCollection.Remove(Control value) at System.Windows.Forms.Control.Dispose(Boolean disposing) at System.ComponentModel.Component.Dispose() at Syncfusion.Windows.Forms.Grid.GridTextBoxCellRenderer.Dispose(Boolean disposing) at Syncfusion.ComponentModel.NonFinalizeDisposable.Dispose() at Syncfusion.Windows.Forms.Grid.GridCellRendererCollection.Clear() at Syncfusion.Windows.Forms.Grid.GridCellRendererCollection.Dispose(Boolean disposing) at Syncfusion.ComponentModel.NonFinalizeDisposable.Dispose() at Syncfusion.Windows.Forms.Grid.GridControlBase.Dispose(Boolean disposing) at Syncfusion.Windows.Forms.Grid.GridControlBaseImp.Dispose(Boolean disposing) at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.Dispose(Boolean disposing) at System.ComponentModel.Component.Dispose() at System.Windows.Forms.Control.Dispose(Boolean disposing) at System.Windows.Forms.ContainerControl.Dispose(Boolean disposing) at System.Windows.Forms.Form.Dispose(Boolean disposing) Grid DataSource property is set to null before disposing

Before zapping the grid, try making sure there is not an active current cell with code like this.grid.CurrentCell(-1, -1); You should upgrade to release 2.0.5.1. 2.0.3.0 is a beta release.

grid.CurrentCell.MoveTo(-1,-1) to be precise... Unfortunately, it does not work. I have the same exception. I even tried to clear current selection like grid.Model.SelectedRanges.Clear(); but it caused other exception when I try to set grid.DataSource=null The other exception says: catched at Syncfusion.Windows.Forms.Grid.GridTextBoxControl.WndProc(Message& msg) System.NullReferenceException: Object reference not set to an instance of an object. at Syncfusion.Windows.Forms.Grid.GridModel.get_Item(Int32 rowIndex, Int32 colIndex) at Syncfusion.Windows.Forms.Grid.GridControlBase.GetViewStyleInfo(Int32 rowIndex, Int32 colIndex, Boolean forceQueryCellInfo) at Syncfusion.Windows.Forms.Grid.GridControlBase.GetViewStyleInfo(Int32 rowIndex, Int32 colIndex) at Syncfusion.Windows.Forms.Grid.GridControlBase.GetCellRenderer(Int32 rowIndex, Int32 colIndex) at Syncfusion.Windows.Forms.Grid.GridCurrentCell.Activate(Int32 rowIndex, Int32 colIndex, GridSetCurrentCellOptions options) at Syncfusion.Windows.Forms.Grid.GridCurrentCell.Activate(Int32 rowIndex, Int32 colIndex) at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.BinderDataSourceChanged(Object sender, EventArgs e) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.OnDataSourceChanged(EventArgs e) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.Set_ListManager(Object newDataSource, String newDataMember, Boolean force, Boolean forceColumnCreation) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.Set_ListManager(Object newDataSource, String newDataMember, Boolean force) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.set_DataMember(String value) at Syncfusion.Windows.Forms.Grid.GridModelDataBinder.set_DataSource(Object value) at Syncfusion.Windows.Forms.Grid.GridDataBoundGrid.set_DataSource(Object value)

Have you tried the release version?
