Hi Enric,

If you want your application to focus on the first row after loading you can set the property IsSynchronizedWithCurrentItem to true.

However, if you want to set the focus to row different than the first one, you should do it by setting the SelectedItem property during Loaded event. For example if you want to set it to the third row, the expression will be:
private void RadGridView_Loaded(object sender, RoutedEventArgs e)
       {
           this.RadGridView.SelectedItem = this.RadGridView.Items[2];
       }

You should also set the RadGridView property EnableLostFocusSelectedState to False if you don't want to show the the unfocused state. This is explained in more details here: link.

Hi  Hristo, It did the trick. It does works.

But my goal is a little bit beyond of your solution. At first I would like to search that row before to select it

Public valuefrom as integer
 Public Sub New(IdPlate as integer)

valuefrom = IdPlate


End Sub


    Private Sub dgvOrdenes_Loaded(sender As Object, e As RoutedEventArgs)
??
how can I retrieve the value provided in "valuefrom" variable without using SQL or LINQ some value in my RadGridView??
        Me.dgvOrdenes.SelectedItem = dgvOrdenes.Items(?????)

End Sub



I've tried use this snippet but does not works because Rows method is not available at all:

Dim lastRow As GridViewRowInfo = RadGridView1.Rows(RadGridView1.Rows.Count - 1)
lastRow.IsSelected = True
For Each rowInfo As GridViewRowInfo In RadGridView1.Rows
    If rowInfo.IsSelected Then
        rowInfo.EnsureVisible()
    End If
Next




Thanks in advance

Hello Enric,

Can you provide me with more information? Do you want to search for a row based on some condition, or you want to get all items satisfying the search condition?

Also please note that RadGridView doesn't have property Rows because the row is a visual element. You should use the property Items when you want to get the item located on a particular row. When RadGridView has enabled virtualization, the only existing items are the items located in the viewport.
