Check/Unchek asp checkbox

I want to check and uncheck several ASP checkboxes with the event of other ASP checkbox.
I want that the checkbox with ID "chkSelecAllGtias" can check and uncheck the checkboxes of the "GridView" with the ID "chkSeleccionarGtia"
Here my ASP code:
<div id="divGtiasLn" runat="server">
<div class="formRow" id="tLineasG" style="padding:10px 20px 20px 20px">
<label style="font-weight:bold">Título de la cabecera</label>
<div class="BotonesOpcion AlineaDerecha">
<div class="label">
Seleccionar Todas
<asp:CheckBox id='chkSelecAllGtias' runat='server'></asp:CheckBox>
</div>
</div>
<div style="width:100%;max-height:350px;overflow:auto">
<asp:GridView ID="rgDatosGtias" runat="server" AutoGenerateColumns="false" EmptyDataText="No se encontraron" DataKeyNames="DataField1,DataField2,DataField3,DataField4" AlternatingRowStyle-BackColor="#DAE2E8">
<Columns>
<asp:TemplateField HeaderText="Seleccionar">
<ItemTemplate>
<asp:CheckBox ID="chkSeleccionarGtia" runat="server" AutoPostBack="true" OnCheckedChanged="chkSeleccionarGtia_Check" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="DataField1" HeaderText="Número1" />
<asp:BoundField DataField="DataField2" HeaderText="Número2" Visible="false" />
<asp:BoundField DataField="DataField3" HeaderText="Número3" />
<asp:BoundField DataField="DataField4" HeaderText="Número4" />
<asp:BoundField DataField="DataField5" HeaderText="Número5" />
<asp:BoundField DataField="DataField6" HeaderText="" Visible="false" />
<asp:BoundField DataField="DataField7" HeaderText="" Visible="false" />
<asp:BoundField DataField="DataField8" HeaderText="" Visible="false" />
</Columns>
</asp:GridView>
</div>
</div>
</div>
My C# code:
protected void Page_Load(object sender, EventArgs e)
{
try
{
chkSelecAllGtias.Attributes.Add("OnClick", "SeleccionarTodasGtias();");
}
catch (Exception ex)
{
msjError.MostrarInfo(ex.InnerException.Message);
}
}
And my JS code:
function SeleccionarTodasGtias() {
console.log("Dentro");
$('#chkSeleccionarGtia').prop('checked', true);
$('#chkSeleccionarGtia').prop('checked', false);
$('#chkSelecAllGtias').prop('checked', true);
$('#chkSelecAllGtias').prop('checked', false);
//$('<=chkSelecAllGtias.ClientID%>').attr('checked', false);
//var objState1 = $find("<%= chkSelecAllGtias.ClientID %>");
console.log("objState1 -> " + objState1);
if (document.getElementById('chkSelecAllGtias').checked == true) {
document.getElementById('chkSeleccionarGtia').checked = true;
alert("true");
}
else {
document.getElementById('chkSeleccionarGtia').checked = false;
alert("false");
}
}
I have tried with only JS but it did not work.
And some combinations of this:
$("#Checkbox1").prop('checked', true); //// To check
$("#Checkbox1").prop('checked', false); //// To un check
And it didn't work
You can do it like this (my example has check box at botton, but it don't matter.
So, this:
<asp:CheckBox id='chkSelecAllGtias' runat='server'
onclick="myheadcheck(this)" >
</asp:CheckBox>
<script>
function myheadcheck(btn) {
// get the ONE check box, checked, or not???
var bolChecked = $(btn).is(':checked')
// now set all check boxes
MyTable = $('#<%= grdEmp.ClientID %>') // select and get grid
MyCheckBoxs = MyTable.find('input:checkbox') // select all check boxes in grid
MyCheckBoxs.each(function () {
$(this).prop('checked', bolChecked)
})
}
</script>
So, I don't have your data, but say I have this gridview, and then a check box.
So, this:
<h3>Select Hotels</h3>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataKeyNames="ID" CssClass="table table-hover" width="50%">
<Columns>
<asp:BoundField DataField="FirstName" HeaderText="FirstName" />
<asp:BoundField DataField="LastName" HeaderText="LastName" />
<asp:BoundField DataField="HotelName" HeaderText="HotelName" />
<asp:BoundField DataField="City" HeaderText="City" />
<asp:BoundField DataField="Description" HeaderText="Description" />
<asp:TemplateField HeaderText="Select" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="chkSel" runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:CheckBox ID="chkHeader" runat="server" Text="Select/unselect All" onclick="myheadcheck(this)" />
<script>
function myheadcheck(btn) {
// get the ONE check box, checked, or not???
var bolChecked = $(btn).is(':checked')
// now set all check boxes
MyTable = $('#<%= GridView1.ClientID %>') // select and get grid
MyCheckBoxs = MyTable.find('input:checkbox') // select all check boxes in grid
MyCheckBoxs.each(function () {
$(this).prop('checked', bolChecked)
})
}
</script>
Code to load is thus this:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
LoadGrid();
}
}
protected void LoadGrid()
{
using (SqlConnection conn = new SqlConnection(Properties.Settings.Default.TEST4))
{
string strSQL = "SELECT * FROM tblHotelsA ORDER BY HotelName";
using (SqlCommand cmdSQL = new SqlCommand(strSQL, conn))
{
DataTable rstData = new DataTable();
conn.Open();
rstData.Load(cmdSQL.ExecuteReader());
GridView1.DataSource = rstData;
GridView1.DataBind();
}
}
}
And now we get/see this:
function CheckAll() {
var chk = $(".chkall").prop("checked");
$("<checkbox name> input:checkbox").each(function (index, item) {
$(item).prop("checked", chk);
});
}

Hide/Show Button based on status if row selected - Javascript

I hope I can be of help. I could not find anything like this in javascript.
I did in C # code, but I could use in Javascript for faster page and related transactions.
My situation is this:
I have to hide or display two buttons depending on the choice of a selected line taking into account the value of a particular field.
How to bring it in Javascript?
For now I've done this:
<script type="text/javascript">
function cbCheck_CheckedChanged()
{
List<object> ListStatoIns = new List<object>();
try
{
if (ListStatoIns != null)
{
if (ListStatoIns.Exists(x => x.Equals(true)) && ListStatoIns.Exists(x => x.Equals(false)))
{
btnApriInserimenti.style.display = "block";
btnChiudiInserimenti.style.display = "block";
}
else if (!ListStatoIns.Exists(x => x.Equals(true)))
{
btnChiudiInserimenti.style.display = "none";
btnChiudiInserimenti.style.display = "block";
}
else if (!ListStatoIns.Exists(x => x.Equals(false)))
{
btnChiudiInserimenti.style.display = "block";
btnChiudiInserimenti.style.display = "none";
}
}
}
catch (err) { }
}
</script>

Iterate Gridview to find greatest value using Javascript or jQuery

I have a gridview and scenario is: once someone deletes a row, it checks if NOTIF_RECIP_SEQ_NBR is maximum or not. If yes then it deletes that row else give a popup.
So basically once someone click on delete, it gets the NOtif_recip_Id of that row and iterates through Gridview to see if NOTIF_RECIP_SEQ_NBR of any row corresponding to that NOTIF_RECIP_ID is greater or not.
Question is It possible at client side? I did it with server side but I don't think that's a good way when I have all data on client side itself.
Please help. I tried multiple ways with Javascript but no use.

Check Box to be selected row index manner in gridview

I want to select the check box values in row index manner in a grid view, Can someone suggest how to select the checkbox? Please find below the code not working appropraitely.
function Check_Click(spanChk) {
{
var IsChecked = spanChk.checked;
var Chk = spanChk;
Parent = document.getElementById('Gv1');
var btn = document.getElementById('<%=btnsubmit.ClientID %>');
var items = Parent.getElementsByTagName('input');
var i = 0;
var tot = 0;
for (i = 0; i < items.length; i++) {
if (items[i].checked) {
tot = tot + 1;
if (tot > 2) {
alert('Cannot check more than 2 check boxes');
items[i].checked = false;
return;
}
}
}
}
}

And in the JavaScript, validate the selected CheckBox with its Row and then validate the number of items selected.
function IdExists(elements, id) {
for (var i = 0; i < elements.length; i++) {
if (elements[i].id.indexOf(id) > -1) {
return true;
}
}
return false;
}
function Check_Click(chkBx) {
Parent = document.getElementById('<% =Gv1.ClientID %>');
for (i = 0; i < Parent.rows.length; i++) {
var row = Parent.rows[i];
var items = row.getElementsByTagName('input');
if (items.length > 0) {
if (IdExists(items, chkBx.id)) {
var tot = 0;
for (j = 0; j < items.length; j++) {
if (items[j].type == 'checkbox' && items[j].checked) {
tot = tot + 1;
if (tot > 2) {
alert('Cannot check more than 2 check boxes');
chkBx.checked = false;
return;
}
}
}
}
}
}
}
You need to add a class name in the checkbox. then you can easily get all the checkbox by the class name.
function Check_Click(spanChk) {
{
var IsChecked = spanChk.checked;
var items = document.getElementsByClassName('myCheckBox');
var i = 0;
var tot = 0;
for (i = 0; i < items.length; i++) {
if (items[i].checked) {
tot = tot + 1;
if (tot > 2) {
alert('Cannot check more than 2 check boxes');
items[i].checked = false;
return;
}
}
}
}
}
UPDATE:
you can also use the below code to get all the checkbox.
var Checkboxes = document.querySelectorAll('input[type=checkbox]');

Insert data from grid view to sql server

I am doing project on asp.net. Right now I have got problem with insert data from gridview to sql server. In my gridview I have add a template as a textbox in order to input value. My problem is about insert value from textbox of gridview to sql server. My code as below:
<%# Page Title="" Language="C#" MasterPageFile="~/coca.Master" AutoEventWireup="true" CodeBehind="Orders.aspx.cs" Inherits="AssignmentWeb.Orders" %>
<%# Import Namespace="System.Data" %>
<%# Import Namespace="System.Data.SqlClient" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<div class="center">
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$("[id*=txtQty]").val("0");
});
$("[id*=txtQty]").live("change", function () {
if (isNaN(parseInt($(this).val()))) {
$(this).val('0');
} else {
$(this).val(parseInt($(this).val()).toString());
}
});
$("[id*=txtQty]").live("keyup", function () {
if (!jQuery.trim($(this).val()) == '') {
if (!isNaN(parseFloat($(this).val()))) {
var row = $(this).closest("tr");
$("[id*=lblTotal]", row).html(parseFloat($(".price", row).html()) * parseFloat($(this).val()));
}
} else {
$(this).val('');
}
var grandTotal = 0;
$("[id*=lblTotal]").each(function () {
grandTotal = grandTotal + parseFloat($(this).html());
});
$("[id*=lblGrandTotal]").html(grandTotal.toString());
});
</script>

Grand Total:

<br />
<asp:Button ID="btnOrder" runat="server" Text="Order!" Width="100px" OnClick="btnOrder_Click"/>
<br />
<br />
</div>
</asp:Content>
<script runat="server">
public void btnOrder_Click(object sender, EventArgs e)
{
int c = 0;
for (int i = 0; i < GridView1.Rows.Count; i++)
{
GridViewRow row = GridView1.Rows[i];
SqlCommand cmd = new SqlCommand();
cmd.Connection = new SqlConnection("Data Source=LIDA-PC; Initial Catalog=InventoryRouting; Integrated Security=True");
//cmd.CommandText = "insert into orders values('" + Session["Username"].ToString() + "',#ProductID, #ProductName, #QtyOrder, #Total)";
cmd.CommandText = "insert into orders values('" + Session["Username"].ToString() + "',#ProductID , #ProductName, #QtyOrder, #Total)";

cmd.Parameters.AddWithValue("#ProductID", GridView1.Rows[i].Cells[0].Text);
cmd.Parameters.AddWithValue("#ProductName", GridView1.Rows[i].Cells[1].Text);
cmd.Parameters.AddWithValue("#QtyOrder", GridView1.Rows[i].Cells[4].Text);
cmd.Parameters.AddWithValue("#Total", GridView1.Rows[i].Cells[5].Text);
//InsertCommand = new SqlCommand("INSERT INTO [orders] ([client], [product], [amount], [price]) VALUES ('" + Session["Username"].ToString() + "', #ProductName, #AverageProduct, #QtyOrder, #Total)");
cmd.ExecuteNonQuery();
cmd.Connection.Close();
c = c + 1;
}
}
</script>
You need to convert grid view row cell control to the appropriate control explicitly.
access like this ((Textbox)(GridView1.Rows[i].Cells[4].Controls[0]).Text for your #QtyOrder
and ((Label)(GridView1.Rows[i].Cells[5].Controls[0]).Text for #Total.
OR
(GridView1.Rows[i].FindControl("txtQty") as TextBox).Text
Thanks.
