get checkbox value client side from multi column

[Kieran]

Hi

I have a multi column combo defined. One column contains standard checkboxes (<input type=checkbox>) How do I get at these checkboxes and their checked state, and indeed for that matter, any value or object in a multi column combo box using javascript?

Any pointers appreciated

Many thanks

Hello Kieran,

Here is a sample code for this:

<telerik:RadComboBox ID="RadComboBox1" runat="server" AllowCustomText="true" Width="240px">
    <ItemTemplate>
        <div>
            <input type="checkbox" checked="checked" id="chk1">
            <asp:Label runat="server" ID="Label1">
                 <%#DataBinder.Eval(Container, "Text")%>
            </asp:Label>
        </div>
    </ItemTemplate>
</telerik:RadComboBox>

you can get the checkbox and label on the client like this:

var comboBox = $find("<%=RadComboBox1.ClientID %>");
for (var i = 0; i < comboBox.get_items().get_count(); i++) {
    var item = comboBox.get_items().getItem(i);
    var checkbox = $telerik.findElement(item.get_element(), "chk1");
    alert(checkbox.checked);
    var label = $telerik.findElement(item.get_element(), "Label1")
    alert(label.innerHTML);
}

Hope this helps.

Kind regards,

 for (var i = 0; i < sender.get_items().get_count(); i++) {
        var item = sender.get_items().getItem(i);
        var checkbox = item.get_checkBoxElement();
        if (checkbox.checked) {
}}

I hope this will save someone's time.
