Repeater Control

I have a repeater Control, within which I have placed checkboxes inside the item template. The No. of checkboxes depends on the number of records present in the database table.

Now I have a task in which I have to check those checkboxes which reside inside the repeater, their checked value depends on the bit value picked from the database. So how will I do that?? My motive is to set their check state while they are loaded inside a repeater during the databound.

Thanks in advance

I have done something similar:

Code:

---

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucAllergyGroup.ascx.cs" Inherits="OnTheRoadMd.Web.ctrls.ucAllergyGroup" %>
<label><span id="spanAllergyTitles" runat="server" enableviewstate="false" class="GroupTitles">Title</span><a id="anchorViewList" runat="server" enableviewstate="false" class="GroupTitles">{view list}</a></label>
<div id="divAllergy" runat="server" enableviewstate="false">
        <asp:repeater id="rptAllergy" runat="server" EnableViewState="false"
                onitemdatabound="rptAllergy_ItemDataBound">
                <ItemTemplate>
        <asp:CheckBox ID="CheckBoxAllergy" runat="server" />
        <asp:Label ID="lblAllergy" runat="server" AssociatedControlID="CheckBoxAllergy" CssClass="labelInlineBlock"></asp:Label>
                </ItemTemplate>
                <SeparatorTemplate><br /></SeparatorTemplate>
        </asp:repeater>                       
</div>
