function populateText() { if(document.getElementById('chechboxid').checked) { var str=document.getElementById('textbox1id).value;// textbox in which you enter data document.getElementById('textbox2id).Value= str; } } call the javascrip function as attribute to checkbox in pageload method of your .aspx page pageload() { checkboxid.attributes.add("onclick","populateText();"); }
Hi,
You can do like this in javascript,
<asp:TextBox ID="txt1" runat="server"></asp:TextBox> <asp:TextBox ID="txt2" runat="server"></asp:TextBox> <asp:CheckBox ID="chk" runat="server" Text="Copy" onclick="copyvalue()"/> <script type="text/javascript"> function copyvalue() { var txt1 = document.getElementById("<%= txt1.ClientID %>").value; document.getElementById("<%= txt2.ClientID %>").value = txt1; } </script>
OR
with jquery
<asp:TextBox ID="txt1" runat="server"></asp:TextBox> <asp:TextBox ID="txt2" runat="server"></asp:TextBox> <asp:CheckBox ID="chk" runat="server" Text="Copy"/> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <script type="text/javascript">
("#<%= chk.ClientID %>").change(function () { var txt1 =
