Question

I am trying to display 3 values in a message box when the user clicks Submit as a means to verify correct input.

The 3 values come from comboBoxes in the form: age, height, weight.

In my current set up, the box will only say “age:” with the actual numerical value in the top border.

How can I get the 3 comboBox data items to appear inside a message box with appropriate titles?

Like this:
Age: 27
Height: 62
weight: 180

Data are stored in the variables age_Num.Text, height_Num.Text, and weight_Num.Text

MessageBox.Show("Age:", age_Num.Text); //just shows "Age:". Value is in titlebar of mb

Answer 1

You must concatenate those values into a single string. Try this, using StringBuilder:

        StringBuilder MessageText = new StringBuilder();
        MessageText.AppendLine(string.Format("Age: {0}", age_Num.Text));
        MessageText.AppendLine(string.Format("Height: {0}", height_Num.Text));
        MessageText.AppendLine(string.Format("Weight: {0}", weight_Num.Text));
        MessageBox.Show(MessageText.ToString());
