Programatically selecting some text in a cell

[Roy Muller]

Greetings,

I'd like to provide a text search function to search cell contents. The Cell Types are TextBox and are set to read-only. How can I select the matching subset of the text within a cell (as if the user highlighted it with the mouse)?

On a related note, I found the grid.SetTopRow() method... is there a similar method to determine if a particular cell is visible?

Here is some code that will highlight the text in a cell. It makes sure the proper cell is active and being edited as this is the only way you can display selected text in a cell currently. Now if you want to simultaneously select text in several cells, that would require a custom cell control with you drawing the selection rectangle yourself within the cell. This code uses the standard selection process of the edit control which is only available for the currentcell.

Public Sub SelectCellText(ByVal row As Integer, ByVal col As Integer, ByVal selStart As Integer, ByVal selLength As Integer)
        Try
            Me.GridControl1.Focus()
            If Not Me.GridControl1.CurrentCell.HasCurrentCellAt(row, col) Then
                Me.GridControl1.CurrentCell.MoveTo(row, col, Syncfusion.Windows.Forms.Grid.GridSetCurrentCellOptions.SetFocus Or Syncfusion.Windows.Forms.Grid.GridSetCurrentCellOptions.ScrollInView, False)
            ElseIf Not Me.GridControl1.CurrentCell.IsEditing Then
                Me.GridControl1.CurrentCell.BeginEdit()
            End If

            Dim tb As GridTextBoxControl = CType(Me.GridControl1.CurrentCell.Renderer.Control, GridTextBoxControl)
            tb.SelectionLength = selLength
            tb.SelectionStart = selStart
        Catch

        End Try
    End Sub

To decide whether a cell is visible or not, you can use the methods GridControl.ViewLayout.IsColVisible and GridControl.ViewLayout.IsRowVisible.
