I have a string in the format ["0,1,0,1,1,0,1,0,0"]. Where 1 represents checked and 0 is not checked. I also have a grid where I have a checkbox in the first column. I need to checkboxes according to my string. I tried at first using JavaScript, but I could not.

C #:

 protected void Page_Load(object sender, EventArgs e)
{
Session["Checados"] = Checados;
.
.
.
}

JS and Aspx:

 <div class="CentralizarGrid">
    <asp:GridView ID="_gvPontoParada" CssClass="table table-striped grid-table" runat="server" AutoGenerateColumns="False" EnableModelValidation="True" CellPadding="4" ForeColor="#333333" GridLines="None" OnDataBound="_gvPontoParada_DataBound" >
        <AlternatingRowStyle BackColor="White" />
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:CheckBox ID="chkRow" runat="server"/>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField HeaderText="Código" DataField="Codigo" />
            <asp:BoundField HeaderText="Descrição" DataField="Descricao" />
            <asp:BoundField HeaderText="Endereço" DataField="Endereco" />

        </Columns>
        <EditRowStyle BackColor="#2461BF" />
        <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
        <RowStyle BackColor="#EFF3FB" />
        <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
    </asp:GridView>
</div>
 .
 .
 .

  <script type="text/javascript">
    var Checados='<%= (Session["Checados"].ToString())%>';
    var check= Checados.split(",");


    function verifica(chk) {
        for(var i = 0; i < check.length; i++)
        {
            if (check[i] == "0")
            {
                document.getElementById(chk).checked = false;
            } else if (check[i] == "1")
            {
                document.getElementById(chk).checked = true;
            }
         }
    }

Thanks for the help !!

As you getElementById and is not iterating over the various checkbox what happens is that the checkbox will always have the value equal to the last element of the Checked vector of your example, your code would have to stay in the following logic:

$(document).ready(function(){
    var i = 0;

    var Checados='<%= (Session["Checados"].ToString())%>';
    var check= Checados.split(","); 

    $('input[type=checkbox]').each(function () {
         $(this).prop('checked',check[i] == '1' ? true : false); 
         i+=1;
     });
 });

In this example you go through all the imputs of type checkbox set to true if the position of the equivalent vector is equal to 1, otherwise false.
