Hi, all

I have a gridview, the first column is checkbox, the page size of gridview is 50.
Now i want to give the range for selecting check boxes in the gridview. Ex.If i give 1-5 means that 1 to 5 rows checkboxes need to select in the gridview.Grid have the paging also. In every page the range must be in 1 to 50 only. Can any body help me. Its urgent. Thank in advance.

Here the code:
<asp:GridView ID="grvRecords" runat ="server" AutoGenerateColumns="false" Font-Bold="True"

            Font-Names="Trebuchet MS" Font-Size="10px" AllowPaging="True" 

        onpageindexchanging="grvRecords_PageIndexChanging" PageSize="50" 

        Font-Underline="False" AllowSorting="True" onsorting="grvRecords_Sorting" >
 <asp:TemplateField  >
            <HeaderTemplate >
           <input id="chkAllItems" type="checkbox"  onclick="CheckAllDataGridCheckBoxes('chkItemChecked',document.forms[0].chkAllItems.checked)" value="Check">
            <asp:CheckBox id="chkBulk" runat="server" Width="30px" AutoPostBack="False"> 

and the Script is:(firstno, lastno is the range)
var grid1 = document.getElementById("<%= grvRecords.ClientID %>");
if (grid1.rows.length > 0) {
    for (var i = firstno - 1; i < secondno; i++) {
        var cell = grid1.rows[i].cells[0];

        for (var j = 0; j < cell.childNodes.length; j++) {
            if (cell.childNodes[j].type == "checkbox" && cell.childNodes[j].name=="chkBulk" ) {
                cell.childNodes[j].checked = true;

The above code is not getting output.

This is just an example for your scenario:-

protected void Page_Load(object sender, EventArgs e)
            ArrayList arr = new ArrayList();

            GridView1.DataSource = arr;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
            if (e.Row.RowType == DataControlRowType.DataRow)
                CheckBox chk = (CheckBox)e.Row.FindControl("CheckBox1");

                if (e.Row.RowIndex <= 4)

You can call a button click (Server Button) with css visibility set to hidden and write the code in C# for checking the check boxes inside the Grid View, this would be easier rather than writing the whole code in JavaScript.
