Jquery 2 clicks event

I had a page with many FileUploads and I am having a problem with jQuery to fire up 2 .click events to remove files at the certain point when a RadioBoxList .click(is selected) event, two buttons calling same function as delete_Click on code behind..
My code as following :
<asp:Button ID="delBtn1" runat="server" Text="DeleteFile" OnClick="delete_Click" ClientIDMode="Static" />
<asp:Button ID="delBtn2" runat="server" Text="DeleteFile" OnClick="delete_Click" ClientIDMode="Static" />
$("#rblist").click(function() {
if ($("#rbl_1").prop("checked")) {
$(".someclass").hide();
uploadCheck1();
uploadCheck2();
$("delBtn1").click();
$('delBtn2').click();
}
});
first click never fired, wondering where is the problem? I am new to jQuery and hoping someone can point out my mistake,thank you!

You need ClientID to get ASP.NET controls with jQuery:
$('#<%= rblist.ClientID %>').click(function() {
if ($('#<%= rbl_1.ClientID %>').prop("checked")) {
$(".someclass").hide();
uploadCheck1();
uploadCheck2();
$('#<%= delBtn1.ClientID %>').click();
$('#<%= delBtn2.ClientID %>').click();
}
});

Use the dblclick event
$(document).ready(function(){
$("p").dblclick(function(){
alert("The the page.");
});
});

you are selecting the button control with id so you need to specify the Jquery id selector(#)
try below code
$("#rblist").click(function() {
if ($("#rbl_1").prop("checked")) {
$(".someclass").hide();
uploadCheck1();
uploadCheck2();
$("#delBtn1").click(); //change here
$('#delBtn2').click();//change here
}
});

JS function calling from the code behind Issue

I have a JS function (Show alert box), and have a link button in ASP page, On click event from code behind for this link button I want to call this function and then redirect to certain page.
ASP Code
<script type="text/javascript" language="javascript">
function myFunction() {
// executes when HTML-Document is loaded and DOM is ready
alert("document is ready!");
}
</script>
<div>
<asp:LinkButton ID="lnkbtnChangePassword" runat="server" Text="Change Passwrod" OnClick="lnkbtnChangePassword_Click" ></asp:LinkButton>
</div>
C# Code
protected void lnkbtnChangePassword_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "myFunction()", true);
Response.Redirect("myPage.aspx");
}
Here when I click on the link button, it simply don't display the alert box/window and redirect to the page.

You should use LinkButton.ClientClick instead of LinkButton.Click event.
Click event is handled on server. When user clicks the button, page is posted back to server and code is executed on server side.
ClientClick event is really a name of JavaScript function which should be executed.
You should probably do something like this:
<asp:LinkButton ID="lnkbtnChangePassword" runat="server" Text="Change Passwrod" OnClientClick="showMyAlertAndSubmit()"></asp:LinkButton>
<script type="text/javascript">
function showMyAlertAndSubmit(){
alert("Your password is being changed");
// submit your form
}
</script>
Why your current code doesn't work
You currently send script for showing a message, and redirect at the same time. This means that browser receives instructions to show a message and to redirect, and it redirects the user before showing the message. One approach could be to redirect from client side. For example:
protected void lnkbtnChangePassword_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(), "CallMyFunction", "myFunction()", true);
}
and on client side
function myFunction() {
// show your message here
// do other things you need
// and then redirect here. Don't redirect from server side with Response.Redirect
window.location = "http://myserver/myPage.aspx";
}
Other options
Since you need to first perform checks on server side before saving data and redirecting, you can use ajax to call server without performing postback.
Remove Click handler, and only use ClientClick:
function myFunction() {
$.ajax({
type: "POST",
url: "myPage.aspx/MyCheckMethod",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
ShowAlert();
window.location = "http://myserver/mypage.aspx";
}
});
}
For more details please check this tutorial.

Change your code like this:
ASP Code
<script type="text/javascript" language="javascript">
function myFunction() {
// executes when HTML-Document is loaded and DOM is ready
alert("document is ready!");
}
</script>
<div>
<asp:LinkButton ID="lnkbtnChangePassword" runat="server" Text="Change Passwrod" OnClick="lnkbtnChangePassword_Click" OnClientClick="myFunction()" ></asp:LinkButton>
</div>
C# Code
protected void lnkbtnChangePassword_Click(object sender, EventArgs e)
{
Response.Redirect("myPage.aspx");
}

Change your javascript function to :
<script type="text/javascript" language="javascript">
function myFunction() {
// alert will stop js execution
alert("document is ready!");
// then reload your page
__doPostBack('pagename','parameter');
}
</script>
And call it from code-behind with this function :
protected void lnkbtnChangePassword_Click(object sender, EventArgs e)
{
//do your job here
//then call your js function
ScriptManager.RegisterStartupScript(this,this.GetType(), "CallMyFunction", "myFunction();", true);
}

What you're missing is waiting for JavaScript alert dialog to popup and then redirect to the page.
In order to do this you need to tell button to wait for JavaScript alert dialog to popup and then do the Server side work after.
ASPX:
<head runat="server">
<title></title>
<script type="text/javascript">
function alertBeforeSubmit() {
return alert('Document Ready');
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button Text="Do" runat="server" ID="btnSubmit" OnClick="btnSubmit_Click" OnClientClick="return alertBeforeSubmit();" />
</div>
</form>
</body>
CS:
protected void btnSubmit_Click(object sender, EventArgs e)
{
Response.Redirect("Default.aspx");
}

native html element input bind to asp.net event behind code

hello guys im using a normal element "input text" now what im trying to do is bind my "input text" into an event handler under asp.net behind code method sample
normal scenario using asp.net element
aspx
<asp:TextBox ID="txtasptext" runat="server" OnTextChanged="txtasptext" ></asp:TextBox>
aspx.cs
protected void txtasptext(object sender, EventArgs e)
{
string name = "hello asp element";
}
but my goal is using normal element text, see below
aspx
<input type="text" id="txtnormaltext" runat="server" />
aspx.cs
protected void txtnormaltext(object sender, EventArgs e)
{
string name = "hello normal element";
}
need some help thanks and happy new year everyone

You could use javascript and AJAX call a web service:
<script>
function doSomething()
{
var params = $('#txtnormal').val();
$.ajax({
type: "POST",
url: "AjaxHandler.asmx/DoSomethingMethod",
data: params,
dataType: "json",
error: function (e) { alert('exception:' + e); }
});
}
</script>
HTML:
<input type="text" id="txtnormaltext" onchange="doSomething()" />
AjaxHandler.asmx Web Service:
[WebMethod]
public void DoSomethingMethod(string inputText)
{
//your code
}

For this HTML control you need to find it from your page_load and bind methods to it.
HtmlGenericControl mytxtbox =(HtmlGenericControl) FindControlRecursive(pnl, "textboxID");
mytxtbox.Attributes.Add("textbox_event_name", "Your_C#_Function");
View the FindControlRecursive function from Here

how can i redirect to another page in function that called by btnclick. ASP.NET

I wanna redirect to another page when i call a function
here my button
<button id="test" runat="server" onclick="Button1_Click()"> Button here </button>
here my button action
protected void Button1_click(Object sender, EventArgs e)
{
int ID = 0;
Label5.Visible = false;
ID = Convert.ToInt32(GridView1.Rows[row.RowIndex].Cells[1].Text);
// somthing like
// Server.Transfer("~/Producter/Delete?id="+ id)
// OR
Response.Redirect("~/Producter/Delete?id="+ ID);
}

since you are using regular html button, when clicked, it will execute Button1_Click() on the client side, instead of in code behind.
Change the button to :
<asp:Button ID="test" runat="server" OnClick="Button1_Click" Text="Button here" />

It could be a problem with the binding of the function Button1_Click() to the button. Try checking the Button1's OnClick property to make sure it links to the function Button1_Click().

your Button1_Click function is correct, and I think the way you are calling from object is wrong.
you should either use
<asp:Button ID="btn_test" runat="server" OnClick="Button1_Click" Text="Button" />
protected void Button1_click(Object sender, EventArgs e)
{
int ID = 0;
Label5.Visible = false;
ID = Convert.ToInt32(GridView1.Rows[row.RowIndex].Cells[1].Text);
Response.Redirect("~/Producter/Delete?id="+ ID);
}
or you should use html button object and call a webmethod like below
<script>
$(document).ready(function () {
$('#test').click(function(){
$.ajax({
type: "POST",
url: "Profile.aspx/update_phone",
data: "{'ProfessionalID':''}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function () { }
});
});
});
</script>
<button id="test" runat="server"> Button here </button>
[webmethod]
public static void Button1_click(Object sender, EventArgs e)
{
....
Response.Redirect("~/Producter/Delete?id="+ ID);
}

Try this
Response.Redirect("~/Producter/Delete?id="+ ID,false);

try this;
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$('#test').on('click', function(e){
e.preventDefault();
//using jquery, you must import jquery library for it
$('#buttonHidden').click();
}
</script>
// your button here to call javascript
<button id="test" runat="server"> Button here </button>
// the hidden button just to hold the Button1_Click which is fired from fireClick()
<asp:Button ID="buttonHidden" runat="server" Style="display: none" OnClick="Button1_Click" />
also fix your code behind like this;
protected void Button1_Click(Object sender, EventArgs e)
{
int ID = 0;
Label5.Visible = false;
ID = Convert.ToInt32(GridView1.Rows[row.RowIndex].Cells[1].Text);
// somthing like
// Server.Transfer("~/Producter/Delete?id="+ id)
// OR
Response.Redirect("~/Producter/Delete?id="+ ID);
}

how to create textbox selected event with asp.net - c#

I was wondering how i can trigger an event when a textbox is selected or focused.
My textbox is an asp.net type.
<asp:TextBox ID="TB" runat="server"></asp:TextBox>
When the event is triggered, i would like to do something in code-behind with c#.
thanks in advance for your reply.

We do not have any textbox selected event in asp.net. You can try using text changed event of textbox or you can try using java script as below.
<head runat="server">
<title></title>
<script type="text/javascript">
function RefreshUpdatePanel() {
__doPostBack('<%= Code.ClientID %>', '');
};
</script>
<asp:TextBox ID="Code" runat="server" onkeyup="RefreshUpdatePanel();" AutoPostBack="true" OnTextChanged="Code_TextChanged"></asp:TextBox>
<asp:UpdatePanel ID="Update" runat="server">
<ContentTemplate>
<asp:DropDownList runat="server" ID="DateList" />
<asp:TextBox runat="server" ID="CurrentTime" ></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Code" />
</Triggers>
</asp:UpdatePanel>

oki, so i figured it out by reading on an article on a different page.
check link: http://codingresource.blogspot.no/2010/01/how-to-use-events-like-onblur-onfocus.html
instead of using onblur i use onclick

Their is no serverside onfocus event for asp textbox you can use textchanged event as follows.using update panel of ajax control you can avoid page refreshment.
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True" ontextchanged="TextBox1_TextChanged1" ></asp:TextBox>
protected void TextBox1_TextChanged2(object sender, EventArgs e)
{
}
On Client side onfocus event You can invoke a c# webmethord through ajax call as follows
HTML SOURCE
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#TextBox1").focus(function () {
$.ajax({
type: "POST",
url: "Default.aspx/test",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
}
});
});
});
</script>
C# code
[WebMethod]
public static void test()
{
}
