[RESOLVED] [2005] ComboBox.SelectedItem won't change

This is annoying me to no end.

Code:

---

Public Sub ComboBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles ComboBox1.SelectedIndexChanged

    Me.TextBox1.Text = Me.ComboBox1.SelectedItem.ToString()

End Sub

---

The value of TextBox1.Text is always equal to ComboBox1.Item(0) regardless of what item is selected in the ComboBox. The DropDownStyle is set to DropDownList.

Any ideas?

I would have run that code from the Click rather than SelectedIndexChange.

I just used that as an example. I have several routines that refer to the currently selected item in the ComboBox, but SelectedItem.ToString always returns the string value of Item(0), regardless of what item is selected.

can you post more code?

There really isn't much more to the code than a variation of what is given.

This was the original:

vb Code:

Public Sub SubmitButton_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SubmitButton.Click
 
     With myJob       ' myJob is a custom class
 
           ' AssignMin is a String variable.
           .AssignMin = CType(Me.AssignMinComboBox.SelectedItem, String)
 
     End With
 
End Sub

I tried using this:

vb Code:

.AssignMin = Me.AssignMinComboBox.SelectedItem.ToString()

But I got the same results. AssignMin always equals the string value of Item 0, event if the SelectedIndex is 1 (I tested this with a message box).

This worked for me

Code:

---

Private Sub ComboBox1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.Click
        Label1.Text = ComboBox1.SelectedIndex.ToString()
End Sub

Hack - I'm curious as to how that would work for the mouse-challenged users who like to use their keyboards for everything. Does the click still fire when a selection is made?

No....for all possibilities you would want to code the keypress in case they arrowed through the combo and hit enter, and I used the SelectedValueChanged event to fire the code by just arrow keying through the combo and the index was displayed in the label.

The documentation for the Click event says that it is fired if the enter key is pressed when the control has focus.

Put a messagebox in the click event just to display "Hi"

You can wail away all day long on the enter key and that box won't ever show up. :)

This works for me... So I guess either the event somehow doesn't fire, or ???

Resolution:

Step 1: Open Tool Box
Step 2: Remove 3lb Hammer
Step 3: Commence beating self over head with hammer
Step 4: Realize that you assigned variable to wrong db field after XMLSerialization.
