Java Script Funtion:
function GetSelectedValue() {
var chkBox = document.getElementById("<%=chkList.ClientID%>");
var checkbox = chkBox.getElementsByTagName("input");
var objTextBox = document.getElementById("<%=txtChkValue.ClientID%>");
var counter = 0;
objTextBox.value = "";
for (var i = 0; i < checkbox.length; i++) {
if (checkbox[i].checked) {
var chkBoxText = checkbox[i].parentNode.getElementsByTagName('label');
if (objTextBox.value == "") {
objTextBox.value = chkBoxText[0].innerHTML;
}
else {
objTextBox.value = objTextBox.value + ", " + chkBoxText[0].innerHTML;
}
}
}
}
where chkList is CheckboxList and txtChkValue is Textbox as given below:
<asp:TextBox ID="txtChkValue1" runat="server" CssClass="textbox"
Width="270px" Height="25px"></asp:TextBox>
<asp:CheckBoxList ID="chkList1" runat="server" onclick="GetSelectedValue1();">
