f-es you are correct, this is what i ended up doing.

VB

For Each r As GridViewRow In GridView3.Rows
                                                        Dim GridView4 As GridView = CType(r.FindControl("GridView4"), GridView)
                                                        For Each row As GridViewRow In GridView4.Rows
                                                            Dim CheckBox11 As CheckBox = CType(row.FindControl("CheckBox11"), CheckBox)
                                                            Dim Label100 As Label = CType(row.FindControl("Label100"), Label)
                                                            Dim Label101 As Label = CType(row.FindControl("Label101"), Label)
                                                            Dim Label102 As Label = CType(row.FindControl("Label102"), Label)
                                                            If CheckBox11.Checked = True Then
                                                                ScriptManager.RegisterStartupScript(Me.Page, Me.Page.[GetType](), "showalert", "alert(' Checked!');", True)
                                                            Else
                                                                ScriptManager.RegisterStartupScript(Me.Page, Me.Page.[GetType](), "showalert", "alert(' Not Checked!');", True)
                                                            End If
                                                        Next
                                                    Next

Solution 1

Use FindControl[^]. When controls are nested you use FindControl to get the child control from the parent, then use FindControl on that control to find things inside of it.

so..like this?

Dim GridView4 As GridView = CType(FindControl("GridView3").FindControl("GridView4"), GridView)
For Each row As GridViewRow In GridView4.Rows
Dim CheckBox11 As CheckBox = CType(row.FindControl("CheckBox1"), CheckBox)
Dim Label100 As Label = CType(row.FindControl("Label100"), Label)
Dim Label101 As Label = CType(row.FindControl("Label101"), Label)
Dim Label102 As Label = CType(row.FindControl("Label102"), Label)
If CheckBox11.Checked = True Then
cval2 = ""
Else

End If
Next
