Scrolling to Searched text row

I am trying to scroll into view the row which contains the data on which I am searching. For some reason the row does not come into view when I move to the current cell - it scrolls the rows but does not display the row with the searched in text.

        myGrid.SearchController.SearchColumns.Add("Description")
        myGrid.SearchController.Search(Search.Text)
        myGrid.SearchController.FindNext(Search.Text)
        Dim temp As Syncfusion.WinForms.GridCommon.ScrollAxis.RowColumnIndex = myGrid.SearchController.CurrentRowColumnIndex
        temp.RowIndex += 2
        temp.ColumnIndex = 1
        myGrid.MoveToCurrentCell(temp)
        temp.RowIndex -= 2
        myGrid.MoveToCurrentCell(temp)

As you can see from my code the workaround is to move beyond the row containing the searched text then moving back to the required row. This obviously will not work if the text being searched for is the last row in the grid.

Hi Peter Rutterford, 
 
Thank you for using Syncfusion controls. 
 
We have checked your provided code example. We suspect that, your requirement is that current cell have to move  based on the Find Next Search text. You can achieve this by using the SfDataGrid.SearchController.CurrentRowColumnIndex property. Please refer the below code snippet.   
 
AddHandler button1.Click, AddressOf button1_Click 
 
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click 
                Me.sfDataGrid1.SearchController.SearchColumns.Add("ProductName") 
                Me.sfDataGrid1.SearchController.Search(textBox1.Text) 
                Me.sfDataGrid1.SearchController.FindNext(textBox1.Text) 
                Me.sfDataGrid1.MoveToCurrentCell(Me.sfDataGrid1.SearchController.CurrentRowColumnIndex) 
End Sub

If we have misunderstood your requirement, please provide more information regarding the requirement. This would help us to proceed further.

Thanks for your reply. I have tried your suggestion and also

        myGrid.TableControl.ScrollRows.ScrollInView(myGrid.SearchController.CurrentRowColumnIndex.RowIndex)
        myGrid.TableControl.UpdateScrollBars()

This does not scroll into view correctly either. It may work on the first text search and possibly the second but fails to bring it into view afterwards for any other occurrences. I do not know if it is relevant but I have text wrapping on the column being searched and use

    Private Sub MatsListGrid_QueryRowHeight(ByVal sender As Object, ByVal e As QueryRowHeightEventArgs) Handles myGrid.QueryRowHeight
        Dim autoFitOptions As New RowAutoFitOptions()
        'To get the calculated height from GetAutoRowHeight method.
        Dim autoHeight As Integer

        If myGrid.AutoSizeController.GetAutoRowHeight(e.RowIndex, autoFitOptions, autoHeight) Then
            If autoHeight > 24 Then
                e.Height = autoHeight
                e.Handled = True
            End If
        End If

    End Sub

to adjust the height of the row.

The search works perfectly in that it finds all occurrences of the text being searched, it just does not display them all in view.
