[2005] Datagridview - Tooltip on cells ?

[staticbob]

Hi Guys,

I was wondering if its possible to get the tooltip assigned to a DataGridView Column to show on the cell as well as the column header ? It only seems to show on the column header as default.

Thanks in advance,

Bob

Hi Bob,

Here's an example how to create tooltips for Datagrid Cells.
You can try this;

Public Class DataGridCellTips 
Inherits DataGrid 
 Private hitRow As Integer 
 Private hitCol As Integer 
 Private toolTip1 As System.Windows.Forms.ToolTip 
 
 Public Sub New() 
   hitRow = -1 
   hitCol = -1 
   Me.toolTip1 = New System.Windows.Forms.ToolTip 
   Me.toolTip1.InitialDelay = 1000 
   AddHandler Me.MouseMove, AddressOf HandleMouseMove 
 End Sub 
 
 Private Sub HandleMouseMove(ByVal sender As Object, ByVal e As MouseEventArgs) 
   Dim hti As DataGrid.HitTestInfo = Me.HitTest(New Point(e.X, e.Y)) 
   If hti.Type = DataGrid.HitTestType.Cell AndAlso (Not (hti.Row = hitRow) OrElse Not (hti.Column = hitCol)) Then 
     hitRow = hti.Row 
     hitCol = hti.Column 
     If Not (Me.toolTip1 Is Nothing) AndAlso Me.toolTip1.Active Then 
       Me.toolTip1.Active = False 
     End If 
     Me.toolTip1.SetToolTip(Me, Me(hitRow, hitCol).ToString) 
     Me.toolTip1.Active = True 
   End If 
 End Sub 
End Class

Hope it helps,

sparrow1, the DataGrid and the DataGridView are very different animals.

staticbob, the column's ToolTipText property is specifically for the column header. Each cell has its own ToolTipText property. As a matter of fact, the DataGridViewCell.TooTipText property help topic includes a link to an article entitled "How to: Add ToolTips to Individual Cells in a Windows Forms DataGridView Control". Sound useful?
