Why would this event only work once, the first time I select an item? If I select another item off the list nothing happens.

on Form1, i have a combobox1 where i have 15 values. im using a case statement with those 15 values to decide what is the next form to go to. i need to make sure the user cannot add in his own text to it or click the NEXT button without having any value at all. how do i add these "exceptions" to my code?
i would think any exception would go before the case so that it could tell you didnt put in the right answer before it looks through the case statment and give you a nullexceptionhandler reference.

[Code]...
1. Add Combobox1 to a form and add the above code
2. Run the form
3. Enter some text not in the drop down list or leave the combobox text blank
4. Click the form close button ( the "X" )
5. The error will be displayed, "ERROR - Invalid Entry!"
6. Press OK on the messagebox
This is where something goes wrong. If you click the Dropdown arrow of the combobox, the dropdown list wont stay open. ( unless you hold the mouse button down ). This doesn't happen if you click or tab to another control (like a text box). Then after the messagebox is displayed the ComboBox still works fine.

I have a weird behavior with tabs on a VB.NET form.On a form I have several comboboxes, text boxes, and 2 buttons.I have made sure my tabindex are in the order I desire, meaning combobox1 has tabindex 1, combobox2 tabindex 2, button1 tabindex5,etc..Here is the behavior, when I first open the form, if I tab from combobox1 it jumps directly to the button, instead of combobox2, however once I help things with the mouse, it will tab in the appropriate order.

I want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
OpenFileDialog1.InitialDirectory = "c:\"
OpenFileDialog1.Filter = "CSV Files (*.csv)|*.csv|Text Files (*.txt)|*.txt"

In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?

I was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?
