GridDataBoundGrid - Unbound column 1st col - colwidth not working

Hi I want to set the column width of unbound column i tried in many ways (1) these are my code '----------Loading the column Me.gceDealView.BeginUpdate() ' Copy over bound columns and add one unbound extra column at the end Dim columns As GridBoundColumnsCollection = CType(gceDealView.Binder.InternalColumns.Clone(), GridBoundColumnsCollection) Dim unboundColumn As New GridBoundColumn() Dim extraColHeaders As Integer = 1 ''Dim style As New GridStyleInfo() ''gceDealView.Model.CellModels.Add("DragButton", New DragButtonCellModel(gceDealView.Model)) ''style.BaseStyle = "Standard" ''style.CellType = "DragButton" ''style.Description = "T" unboundColumn.HeaderText = "Y" unboundColumn.MappingName = "Unbound" unboundColumn.StyleInfo.AutoSize = True columns.Add(unboundColumn) gceDealView.Binder.GridBoundColumns = columns Me.gceDealView.Model.Cols.HeaderCount = extraColHeaders Me.gceDealView.Model.Cols.FrozenCount = extraColHeaders Me.gceDealView.Model.Data.ColCount = Me.gceDealView.Model.ColCount AddHandler gceDealView.Model.QueryCellInfo, AddressOf ModelQueryCellInfo gceDealView.Model.ColWidths(1) = 20 gceDealView.Binder.InternalColumns("Unbound").HeaderText = "Y" gceDealView.Model.ColWidths("Unbound") = 20 Me.gceDealView.EndUpdate() Me.gceDealView.Model.ColWidths.ResizeToFit(GridRangeInfo.Table, GridResizeToFitOptions.IncludeHeaders) ' gceDealView.Model.ColWidths(1) = 10 'gceDealView.Model.Cols.FrozenCount = 1 'this is here to hide an extra column at the end ????

'remove when the problem is corrected... Me.Model.Cols.Hidden(Me.Model.ColCount) = True End If Me.Model.ColWidths(0) = 18 ------------------------------------- Both of the above efforts not working the first unbound column has some fixed column width and it can be altered manual after the screen gets loaded. what is the problem where i am missing Thanks Rajaraman

You should try setting the gridDataBoundGrid1.AllowResizeToFit = false to see if this handles this problem for you. If you do not set this property, the grid tries to size things based on headertext, an dthis will step on your explicit sizing. Here is a link to a KB article on sizing columns in a GridDataBoundGrid. http://www.syncfusion.com/KB/Grid/Grid_c35c.asp#q577q
