JQuery or C# to check when "Checked" multi checkbox is true
<p>I select data from database and bind data by asp:Repeater.
I create checkbox in ItemTemplate and receive data from database.
I want to update data in database when I "checked" on checkbox on any rows.</p>

<p>protected void myRepeater_ItemDataBound(Object sender, RepeaterItemEventArgs e)
        { </p>

<pre><code>        //*** Level ID ***//
        Label lblLevelID = (Label)(e.Item.FindControl("lblLevelID"));
        if ((e.Item.FindControl("lblLevelID") != null))
        {
            lblLevelID.Text = DataBinder.Eval(e.Item.DataItem, "LevelID").ToString();
            strLevelID = lblLevelID.Text;
            //MyArr[Convert.ToInt16(In), 0] = strLevelID;
        }
</code></pre>

<p>...</p>

<pre><code>&lt;asp:Repeater id="myRepeater" runat="server" OnItemDataBound="myRepeater_ItemDataBound"&gt;
    &lt;HeaderTemplate&gt;
        &lt;table border="1" style="font-size:12px;" width="800"&gt;
    &lt;/HeaderTemplate&gt;
    &lt;ItemTemplate&gt;  
        &lt;tr&gt;
            &lt;td align="left" width="25"&gt;&lt;asp:Label id="lblLevelID" runat="server"&gt;&lt;/asp:Label&gt;&amp;nbsp;&lt;/td&gt;
            &lt;td align="left" width="350"&gt;&lt;asp:Label id="lblLevelDesc" runat="server"&gt;&lt;/asp:Label&gt;&amp;nbsp;&lt;/td&gt;
            &lt;td align="left" width="25"&gt;&lt;asp:Label id="lblChoiceID" runat="server"&gt;&lt;/asp:Label&gt;&amp;nbsp;&lt;/td&gt;
            &lt;td align="left" width="350"&gt;&lt;asp:Label id="lblChoiceDesc" runat="server"&gt;&lt;/asp:Label&gt;&amp;nbsp;&lt;/td&gt;
            &lt;td align="center" width="50"&gt;&lt;%--&lt;input type="checkbox" id="chkSelected" OnCheckedChanged="chkSelected_OnCheckedChanged"  AutoPostBack="True" /&gt;--%&gt;

            &lt;asp:Label ID="lblTest" runat="server"&gt;&lt;/asp:Label&gt;
            &lt;/td&gt;
        &lt;/tr&gt;           
    &lt;/ItemTemplate&gt;
    &lt;/asp:Repeater&gt;
