Select all items in asp.net CheckBoxList

ASP.NET and C #.

I would like to have a CheckboxList with a Select All element.

  • When this particular item is selected, all others will be selected too.
  • When the choice is removed from this element, so will the other objects from everything.
  • Checking / unchecking any other items will have an effect on this item regardless of the selection status of the Select All item.

I am looking for a jquery solution for this.

Here is the data binding code in my code:

IList<Central> Centrals = new CentralProvider().GetAllCentralsAsList();
Centrals.Insert(0, new Central(){Central_ID = 999, Central_Name = "Select All"});
CentralChecks.DataSource = Centrals;
CentralChecks.DataTextField = "Central_Name";
CentralChecks.DataValueField = "Central_ID";
CentralChecks.DataBind();

And here is the markup:

<div class="CentralDiv" id="CentralDiv">
    <h2>Centrals:</h2>
    <span>
        <asp:TextBox ID="CentralTextBox" runat="server" CssClass="textbox">Centrals</asp:TextBox>
        <img id="CentralArrow" src="images/down_arrow.jpg" style="margin-left: -22px; margin-bottom: -5px" />
    </span>
    <div id="CentralEffect" class="ui-widget-content">
        <asp:CheckBoxList ID="CentralChecks" runat="server" onclick="GetSelectedCentralValue();">
        </asp:CheckBoxList>
    </div>
</div>

Please note that there are several checklist lists on the page, so any solution should consider this.
