suppose you have a checkbox and one button and submit a form on button click with checkbox true or false value according to checkbox checked or uncheck.
create a page which has a checkbox and a button on .aspx page
Student:<asp:CheckBox ID="chkStudent" runat="server" Checked="false" /><br />
<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />
On button click event you want vale of check box checked or unchecked accordingly :
protected void btnSubmit_Click(object sender, EventArgs e)
{
bool student = chkStudent.Checked ? true : false;
}
thereafter you can use student variable for fruther working.
