Dear All,
I have some confusion on data binding between datagridview and textbox.

Issue Description:
I want to bind datatable's data in datagridview and textbox, and when I

clicked the datagridview row, then textbox would get corresponding data in

datagridview and show in textbox. My problem is when I added the new empty row and

then I clicked this row, but can't clear textbox, still remained last row data.

You can check my implementation as below. Thank in advance.

Private Sub InitCPN()

   Me.dgvCPN.DataSource = Me._dsSFC.Tables("CPNInfo")                '''' Binding data table to the data grid view.


   ////Textbox binding datatable.
   Me.txtSN2.DataBindings.Add("Text", Me._dsSFC.Tables("CPNInfo"), "SN2Pattern")
   Me.txtSN3.DataBindings.Add("Text", Me._dsSFC.Tables("CPNInfo"), "SN3Pattern")
   Me.txtSN4.DataBindings.Add("Text", Me._dsSFC.Tables("CPNInfo"), "SN4Pattern")
