DataGridView1 Not Populating On Load?

I am using VB 2008

I created a simple form which has two tableadapters to a Access database. On the form I have a combobox that uses the Category TableAdapter and it populates on load fine. the other control is a DataGridView1 which is popluated by the Message Table Adapter based on which Category is selected. It does NOT populate on LOAD and thats my problem.

So the result I'm looking for is when you run the app and my first form loads it

A. Chooses the frist Category in the list (and it does that fine)

B. Populates the DataGridView1 based on the first Category (this is my problem)
The DataGridView1 does Populate after I re-select the Category in the combobox1.

Here is my code below.

Public Class FunnyMessages
Dim catid As Integer
Private Sub FunnyMessages_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
