I have an editable grid with two image buttons, one an up arrow and another a down arrow. I want to use these two buttons to move rows up and down in the list. From within the OnClick event of the MTImageButton, how do I access other controls in the row? I need the values in these controls to move the current row up or down. Below is the code I'm using but I get a System.NullReferenceException: Object reference not set to an instance of an object error for TPID.

Dim TPID As MTHidden = BookletTemplatePage.GetControl(Of MTHidden)("BookletTemplateID")  
Dim Seq As MTTextBox = BookletTemplatePage.GetControl(Of MTTextBox)("Sequence")  
If Not String.IsNullOrEmpty(TPID.Value) And Not String.IsNullOrEmpty(Seq.Value) Then  
	ISUtility.BookletTemplatePageUtility.MoveTemplatePageUp(TPID.Value, Seq.Value)  
End If  

I'm using the first two lines of the code in the BeforeShow event to hide the button if either of the two controls don't contain a value, so I'm sure the control names are correct.

Nevermind, I found the answer from a similar question I posted six months ago.

((MTButton)sender).Parent.FindControl("<Hidden control name>")
