How To Show Hidden Text Boxes When Items Are Selected In A Combo Box

I have a combo box with 5 different options, 'one player', 'two players', 'three players' etc. My requirement is when user select something from combo box their equivalent text box

Solution 1:

PrivateSub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
    If ComboBox1.Text.Trim.Contains("Player 1") = TrueThen
        TextBox1.Visible = True
        TextBox2.Visible = False
        TextBox3.Visible = FalseElseIf ComboBox1.Text.Trim.Contains("Player 2") = TrueThen
        TextBox1.Visible = True
        TextBox2.Visible = True
        TextBox3.Visible = FalseElseIf ComboBox1.Text.Trim.Contains("Player 3") = TrueThen
        TextBox1.Visible = True
        TextBox2.Visible = True
        TextBox3.Visible = TrueEndIfEndSub

Solution 2:

Simply combine the .change() function available in jquery (https://api.jquery.com/change/) with css visibility (visibility:hidden/visible; check http://www.w3schools.com/cssref/pr_class_visibility.asp )

$( "#myComboBox" ).change(function() {
  //do what you have to do here
});

Solution 3:

Try something like this:

Sub cbC(sender AsObject, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    SelectCase ComboBox1.SelectedIndex
        Case0
            TextBox1.Visible = False
            TextBox2.Visible = FalseCase1
            TextBox1.Visible = True
            TextBox2.Visible = FalseCase2
            TextBox1.Visible = True
            TextBox2.Visible = TrueEndSelectEndSub

Or this, according to what fits better to your needs:

Sub cbC(sender AsObject, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
    TextBox1.Visible = (ComboBox1.SelectedIndex = 0)
    TextBox1.Visible = (ComboBox1.SelectedIndex = 1)
EndSub

Solution 4:

The TextBox1.Visible = (ComboBox1.SelectedIndex = 0) works perfectly.

You must also make sure to set Visible under Properties to False for your textboxes and labels. Otherwise you textboxes will initially be visible when you run application.
