Display textbox using combobox

Hi

how to select the required items in multiple comboboxes to
display individually into multiple textboxes / Label......

Example: Combo item 1 from combobox to display into textbox1
Combo item 2 from combobox2 to display into textbox2


Multiple tasks..

Thanks

TextBox1.Text = ComboBox1.SelectedItem.ToString

Is that what you mean? Not quite clear, though.

Hi

Still cannot...

I want to select the combo items and display into another form
I may select more than one combo boxes...

This is the error:

An unhandled exception of type 'System.NullReferenceException' occurred

Thanks

This is part of my code:

Code:

---

    Private Sub btnAddAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddAdd.Click
     
        Dim lblSubCategory, lblRepeat
        Dim confirm As New Confirm

        If cboSubCategory.Text <> "" And cboRepeat.Text <> "" Then
            lblSubCategory.text = cboSubCategory.SelectedItem.ToString
            lblRepeat.Text = cboRepeat.SelectedItem.ToString
            confirm.Show()
            Me.Hide()
        Else
            MessageBox.Show("Please fill the area", "Missing data", _
            MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
        End If

---

I solve it just because i forgot to put a dot in front the lblSubCategory and lblRepeat....

:cry:

You may pound your head against a brick wall now. :)

Is there a way to make sure that some combo box is a required field to key in and some not....

At the same time, it can be send to display into the textbox..

Thanks

THe combobox has a Tag property, you can store information about the combobox in there, and check it during your validation procedure.

Hi

What you mean by store information...

information is already inside the collection property....
or you means put the combo box name inside the tag...

actually how is this tag really work... i really blur..

Thanks

You said that you want to know whether the ComboBox is a required field or not. What you could do is set it's .Tag() property to "Required".

The Tag property can hold any object, I'd generally use it to hold a string with info about that particular field.

Later, when you are validating the inputs in the form, you can run through and check it's Tag() property to see if it's "Required" and then work accordingly.

I'm only giving you a rough idea, because you have a rough question, but it should do well enough.
