easy! need to calculate one text box when the user enters data into another text box.

swtlbee

I have two text boxes and a C# method/function that will calculate the data of one text box when another is populated:
protected void calcMonthlyIncome()
    {
        appl_annualIncome = Convert.ToInt32;
        appl_monthlyIncome.Text = appl_annualIncome/12;
    }

What I need to know is in my text box how do I call the method/function once the user keys off or tabs off the text box(appl_annualIncome) he entered data into and set focus on the next textbox(appl_monthlyIncome) that will hold the calculated results.

Am new to the .net world - would appreciate any guidance. Thank you

Accepted answer
I think I figured it out:

CODE BEHIND:
protected void calcMonthlyIncome(object sender, EventArgs e)
    {
        decimal annualIncome;
        annualIncome = Convert.ToDecimal(appl_annualIncome.Text);

        appl_monthlyIncome.Text = Convert.ToString(annualIncome/12);
    }

You can use javascript code and onblur of first textbox you can call the second textbox and calculate the prices.

or if you want to do it in pagebehind then follow the code:
.aspx code:
OnTextChanged="txtCity_TextChanged" AutoPostBack="true" runat="server">

.cs code
protected void txtCity_TextChanged(object sender, EventArgs e)
{
// your onblur code should come here
}
