GridDataBoundGrid - Unbound column 1st col - colwidth not working

[Administrator]

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...
' 'gceDealView.Model.Cols.Hidden(gceDealView.Model.ColCount) = True
'gceDealView.Model.ColWidths(0) = 10

'----------
'Quercellinfo
'------------

Private Sub ModelQueryCellInfo(ByVal sender As Object, ByVal e As GridQueryCellInfoEventArgs)
Dim model As GridModel = CType(sender, IGridModelSource).Model
Dim rowIndex As Integer = e.RowIndex
If rowIndex > model.Rows.HeaderCount Then
Dim colIndex As Integer = e.ColIndex
'Unbound checkbox header column
If colIndex = 1 Then
' Initialize appearance of checkbox
e.Style.CellType = "TextBox"
'e.Style.Interior = New BrushInfo(Color.FromArgb(192, 201, 219))
'e.Style.Interior = New BrushInfo(GradientStyle.Horizontal, Color.FromArgb(192, 201, 219), Color.FromArgb(237, 240, 246))
'e.Style.Borders.Right = New GridBorder(GridBorderStyle.Standard, Color.Gray, GridBorderWeight.Thin)
'e.Style.HorizontalAlignment = GridHorizontalAlignment.Left
'e.Style.VerticalAlignment = GridVerticalAlignment.Middle
e.Style.Text = ""
e.Style.ImageList = ImglstDealView
e.Style.ImageIndex = 0
e.Style.Description = "*"
e.Style.Font.Size = 8
e.Style.Font.Bold = False
e.Handled = True
' Syncfusion.Diagnostics.TraceUtil.TraceCurrentMethodInfo(keyColIndex, key, value, e);
Return
End If
'Unbound column in columns collection
Dim fieldNum As Integer = Me.gceDealView.Binder.ColIndexToField(colIndex)
If fieldNum >= 0 Then
Dim col As GridBoundColumn = Me.gceDealView.Binder.GridBoundColumns(fieldNum)
If Not (col Is Nothing) AndAlso col.MappingName = "Unbound" Then
'Select Case rowIndex Mod 4
'e.Style.HorizontalAlignment = GridHorizontalAlignment.Left
'e.Style.VerticalAlignment = GridVerticalAlignment.Middle
e.Style.CellType = "TextBox"
e.Style.ImageList = ImglstDealView
e.Style.ImageIndex = 0
e.Style.Text = ""
e.Style.Description = "*"
e.Style.Font.Size = 8
e.Style.Font.Bold = False
e.Handled = True
'Syncfusion.Diagnostics.TraceUtil.TraceCurrentMethodInfo(keyColIndex, key, value, e);
Return
End If
End If
End If
End Sub

(2) i have tried to change colwidth in syncfusion sample at the end of the following snippet

GDBGWithDropGrids sample has this code in Class GridHierDataBoundGrid
---------------------------
'this.Model.ColWidths.ResizeToFit(GridRangeInfo.Row(0));
'set the width of th erow headers
If hasChildGrid Then
Me.Model.ColWidths(1) = 18
Me.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

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.
