Hi.
I want display a grid all readonly.
The user can’t select cell, cant’ select rows…. can do nothing!
I want to show some information in the grid and select a row programmatically, based on some calculation.

How can i do this?

Thanks.

Try this:
– set the <b>AllowCellNavigation</b> property of the GridControl to <b>false</b>
– set the <b>SelectionMode</b> property of the GridControl to <b>SelectionMode.None</b>
– select a row programmatically, by setting the <b>IsSelected</b> property of the row to <b>true</b>

Thanks Tommy for your answer.
I set the property you wrote, but if the user click on the grid the selection is cancelled.

Here is a snippet from my Code:
In InitializeComponent:
‘
‘GridControl1
‘
Me.GridControl1.AllowCellNavigation = False
Me.GridControl1.DataRowTemplate = Me.dataRowTemplate1
Me.GridControl1.FixedHeaderRows.Add(Me.GroupByRow1)
Me.GridControl1.FixedHeaderRows.Add(Me.ColumnManagerRow1)
Me.GridControl1.Location = New System.Drawing.Point(88, 72)
Me.GridControl1.Name = “GridControl1”
‘
‘GridControl1.RowSelectorPane
‘
Me.GridControl1.RowSelectorPane.Visible = False
Me.GridControl1.SelectionMode = System.Windows.Forms.SelectionMode.None
Me.GridControl1.Size = New System.Drawing.Size(440, 176)
Me.GridControl1.TabIndex = 0

m_dtTab3.Columns.Add(“RapPercTab2”, GetType(System.String))

You could catch the <b>IsSelectedChanged</b> event from the datarowtemplate, and in the event handler, you could check to see if the row can be selected. If the row can’t be selected, deselect it. Something like this:<code>Dim row As Xceed.Grid.Row = sender
If row.IsSelected Then
If row can not be selected Then ‘ fill in the right condition here
row.IsSelected = False
End If
End If</code>
