Can't get Label to display value from combo box selection

Question

C# Winforms User control here.

So I have a label object named alcohol. My combo box object is named snryeastTypeComboBox. I want to keep the number for alcohol for math later. I'm trying to display the number in a label yet it isn't working... any ideas?

public void snryeastTypeComboBox_TextChanged(object sender, EventArgs e)
{
    if (snryeastTypeComboBox.SelectedText == "CSM")
    {
        var alcoholTolerance = 14;
        alcohol.Text = alcoholTolerance.ToString();
    }

Answer 1

Try the following instead:

public void snryeastTypeComboBox_TextChanged(object sender, EventArgs e)
{
    if (snryeastTypeComboBox.Text == "CSM")
    {
        var alcoholTolerance = 14;
        alcohol.Text = alcoholTolerance.ToString();
    }

Replace .SelectedText with just .Text.

Answer 2

To understand your question, I think you need to fire the event when you select a value from your combo box. If that is the case you should subscribe to SelectedIndexChanged event instead of TextChanged .

TextChanged event should be used if the user can change the value by typing in your combo box.

Answer 3

To achieve this your code needs to be written inside the event SelectedIndexChanged instead of TextChanged .

Instead of SelectedText you should use Text

The below code will work fine.

private void snryeastTypeComboBox_SelectedIndexChanged(object sender, EventArgs e)
    {

        if (snryeastTypeComboBox.Text == "CSM")
        {
            var alcoholTolerance = 14;
            alcohol.Text = alcoholTolerance.ToString();
        }

    }
