Here is an example. I hope this can help you

    
               Private Sub RadGridView1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles RadGridView1.MouseDown 
        
                    Dim strValue As String = "" 
        
                    If Not IsNothing(RadGridView1.CurrentRow.ViewInfo.ParentRow) Then 
        
                        strValue = "Parent row: " & RadGridView1.CurrentRow.ViewInfo.ParentRow.ViewInfo.CurrentIndex.ToString & Environment.NewLine 
        
                    End If 
        
                    strValue &= "Current row: " & RadGridView1.CurrentRow.ViewInfo.CurrentIndex.ToString 
        
            MessageBox.Show(strValue) 
        
            End Sub

Hi Jonathan

Thanks for the reply , But i am looking for selecting the third level grid's row through the code.
Currently when i am trying to show a row in third level in hierarchy as selected and highlighted,
first row of grid gets selected.

To demonstrate exact requirement i am attaching a file.

Thanks

Hello Ajay,

In this case, you should expand the child view and set it as current view. After that, you can set any row from the child view as current. Please consider the code snippet below:

this.radGridView1.Rows[1].IsExpanded = true;

Application.DoEvents();

this.radGridView1.CurrentView = this.radGridView1.Rows[1].ChildRow.ChildViewInfo.GridViewElement;

this.radGridView1.Rows[1].ChildRow.ChildViewInfo.Rows[0].IsCurrent = true;

I hope this helps.
