Default Setting Checkbox Checked Property from OnClick


I have a Repeater object displaying data for records returned from a database as well as a 'Select' checkbox for each reord, which is set at 'Checked' by default. I want to put a 'Deselect All' button on the page to allow the user to deselect all the records. How do I access the checked property for each item returned? Here is the Repeater:

<asp:Repeater id="objCountyRepeater" runat="server">
        <table summary="Payee Information" border="0">
            <tr><td><asp:Checkbox id="cbxSelected" checked="True" runat="server" /></td><td colspan="2" width="600" style="text-align:left"><b><asp:Label Text='<%# Container.DataItem("Collectable") %>' runat="server" /> for: </b><asp:Label id="lblEntityName" visible="True" Text='<%# Container.DataItem("EntityName") %>' runat="server" /><asp:Label id="lblEntityOID" visible="False" Text='<%# Container.DataItem("EntityOID") %>' runat="server" /></td><td style="text-align:right"><b>Cert Costs: </b></td><td width="75"><asp:Label id="lblCertFees" Text='<%# DataBinder.Eval(Container.DataItem, "CertFees", "{0:C}") %>' runat="server" /></td></tr>
            ETC. ETC.

You need to loop thru all the repeater's items, test for the right item types then you can find the checkbox control and set its checked property.

      For Each objItem In objCountyRepeater.Items
         Select Case objItem.ItemType
            Case ListItemType.AlternatingItem, ListItemType.Item, ListItemType.SelectedItem
               objCheckBox = CType(objItem.FindControl("cbxSelected"), CheckBox)
               If Not objCheckBox Is Nothing Then
                  objCheckBox.Checked = False
               End If
         End Select

Here's a working example. You can see the code for it there as well.

Work smarter, not harder.
