Visual Studio 2010 Form Checkbox value C#

Question

I created a form page I have several check boxes and and Text boxes on the form page. Checkboxes named like Group1Group2Group3Group4 and Group5. textbox named as RErrors. I just want to show the value in textbox if check box is checked. (If 5 check box are checked then value will be 5 3 checked means 3 show in text box.) I tried to put the below code but nothing happens. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class Default2 : System.Web.UI. Page { protected void Page_Load( object sender EventArgs e) { int sum = 0; if (Group1.Checked == true ) sum += 1; if (Group2.Checked == true ) sum += 1; if (Group3.Checked == true ) sum += 1; if (Group4.Checked == true ) sum += 1; if (Group5.Checked == true ) sum += 1; //return sum RErrors } }

It depends upon your need If you want the text box to be filled dynamically you have to write event for all the check boxes. You can also calculate it on button click event which turns out to be very simple.

Thanks. Yes I need to show the value dynamically. Do I need to do the check box click event each checkbox ?

Hi Prasad You have written your code in page load where there is no check box checkedIf you need to show the number of check box checked(Dynamically) you have to write the code in Javascript for Click event of the Check boxes. If you don't want to display the value dynamically means on page load itself if you are having some check boxes checked the current code will work. Just assign the value of Sum to textboxid.text property.
