I put the numeric value in front of Basic Salary's usercontrol.. till then its fine.. But when i delete the values from usercontrol11 , some error is coming ... I m unable to solve this... please help me.. Here is my Demo folder.. Download Demo.rar[^] 2 ) Demo1 In this 'Demo1' project.. Again I created few labels and now with textboxes. I put the numeric value in front of Basic Salary's textbox.. till then its fine.. But when i delete the values from textbox1 , same error is coming ... If possible please try to help me..

Your title is a waste of time

Thats nice, but is it really relevant?

Do you think that telling us the error would help us in answering your question? Plus, excuse my laziness, but I really cant be bothered downloading your project (which incidentally I have no way of verifing is legitimate) in order to help you out. The error message, plus some relevant code should more than suffice.

Please try for a more intelligent header.

Try posting code and the error text, not expect people to download your project.

Probably for the same reason. I would guess you have code that expects a number in there and blows up when there isn't one. Instead of int.Parse, use int.TryParse.

Christian Graus No longer a Microsoft MVP, but still happy to answer your questions.

Hello.. The project is only of 30kbs each.. I m afraid. Here is the screenshot of when I use usercontrol.. http://i34.tinypic.com/2z8b905.jpg Code here.. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace Demo { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void userControl11_TextChanged(object sender, EventArgs e) { label6.Text = userControl11.Text; userControl12.Text = Convert.ToString(Convert.ToDouble(userControl11.Text) * .1); userControl13.Text = Convert.ToString(Convert.ToDouble(userControl11.Text) * .01); label6.Text = Convert.ToString(Convert.ToDouble(userControl12.Text)+Convert.ToDouble(userControl13.Text)+Convert.ToDouble(userControl11.Text)); } private void userControl14_TextChanged(object sender, EventArgs e) { label6.Text = Convert.ToString(Convert.ToDouble(userControl12.Text) + Convert.ToDouble(userControl13.Text) + Convert.ToDouble(userControl11.Text)+Convert.ToDouble(userControl14.Text)); } } }
