i have a default.aspx page:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btn" runat="server" Text="clicke here" OnClick="btn_Click"/>
<asp:TextBox ID="txt" runat="server"></asp:TextBox>
<asp:Label runat="server" ID="lbl"></asp:Label>
</div>
</div>
</form>
</body>
</html>
and default.aspx.cs :
public partial class _Default : System.Web.UI.Page
{
string test;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_Click(object sender, EventArgs e)
{
test = txt.Text;
lbl.Text = test;
}
}
now i want to make the dll of my default.aspx.cs file and remove it from the website and give the reference of it.
so how can i do this??
Right click on Properties. Then go to the Application tab and change output type to class library.
Once the dll is created in bin folder, right click on Reference in your project where you want to add the dll. And then add the reference of the dll.
In this case it would be best to create a server control. You can then use it in any ASP.NET Project.
Here is a walkthrough...

I have this WebForm Html:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="GetLink.aspx.cs" Inherits="GetLink" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="hidden" runat="server" id="hdnVal" value="55"/>
</div>
</form>
</body>
</html>
And i want to add to this code a JavaScript function and run it with this code:
protected void Page_Load(object sender, EventArgs e)
{
if (!ClientScript.IsStartupScriptRegistered("key1"))
{
ClientScript.RegisterStartupScript(GetType(), "key1", #"<script type=""text/javascript"">function callMyJSFunction() { document.getElementById(""hdnVal"").value='5'; }</script>");
}
ClientScript.RegisterStartupScript(this.GetType(), "key1", "<script>callMyJSFunction();</script>");
string resutOfExecuteJavaScript = hdnVal.Value;
}
When i run it the value of hdnVal keep the 55 value and not change. Any idea what is the problem?
Your code in Page_Load event should call ClientScript.RegisterClientScriptBlock when registering the JavaScript function of callMyJSFunction, whereas in your code you are registering this function as a startup script. This is the only mistake in your code.
So, if you change your server-side code to as below, then it will work according to your expectations.
protected void Page_Load(object sender, EventArgs e)
{
if (!ClientScript.IsClientScriptBlockRegistered("key1"))
{
//register your javascript function
ClientScript.RegisterClientScriptBlock(GetType(), "key1", #"<script type=""text/javascript"">function callMyJSFunction() { document.getElementById(""hdnVal"").value='5'; }</script>");
}
ClientScript.RegisterStartupScript(this.GetType(), "key1", "<script>callMyJSFunction();</script>");
string resutOfExecuteJavaScript = hdnVal.Value;
}
The first problem is you are creating function in Clientscript while you can simply put the function in javascript and then just do the calling part.Second problem is that the time your function is calling that hiddenfield for view its not available on document simply means stop putting your code on page load and use a button click event instead.Third problem is you are using multiple inverted commas at so many places which aren't required.
This worked for me
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$('document').ready()
{
function callMyJSFunction()
{
debugger;
document.getElementById('hdnVal').value = '5';
alert(document.getElementById('hdnVal').value);
}
// - including fonts, images, etc.
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="hidden" runat="server" id="hdnVal" value="55"/>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</div>
</form>
</body>
</html>
and on cs page
protected void Button1_Click(object sender, EventArgs e)
{
ClientScript.RegisterStartupScript(this.GetType(), "key1", "<script>callMyJSFunction()</script>",false);
string resutOfExecuteJavaScript = hdnVal.Value;
}
iam writing code for button onclient event with js to print the webpage and onclick event for generating pdf and downloading it ..both must be done in a single action..
but when i cancel print which i onclient click event then oncick event is firing .
<script type="text/javascript">
function PrintPage()
{
window.print();
return true;
}
<asp:Button ID="Button3" runat="server" Text="PTPDF" UseSubmitBehavior="false" OnClick="Button3_Click1" OnClientClick ="javascript:PrintPage();" />
</div>
protected void Button3_Click1(object sender, EventArgs e)
{//here is the code for pdf generation,
this code must get fired automatically after onclient click event without users action}
Below code works perfectly on my end and illustrateson how both OnClick and OnClientClick works at a same time-
ASPX -
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Click.aspx.cs" Inherits="Click" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script language="javascript" type="text/javascript">
function confirmthis()
{
document.getElementById('TextBox2').value = 'onclient works';
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" OnClientClick="return confirmthis();" Text="Click Me" /></div>
</div>
</form>
</body>
</html>
Inline code -
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Click : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
TextBox1.Text = "OnClick works";
}
}
Please paste the above code at your end and let me know if it still doesn't work.
Thanks!!
When adding the JQuery JS include the InnetHTML is not working:
My HTML code:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="aaa.aspx.cs" Inherits="aaa" %>
<!DOCTYPE html>

</div>
</div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" style="height: 26px" Text="Button" />
</form>
</body>
</html>
My C# code :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class aaa : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
ppdiv.InnerHtml = "aaa";
}
}
when include JQUery the InnetHTML is not working. Where is the error and how to fix it.
Thanks in advance
i believe it is because you are using runat="server" in head within which you add the jquery. jquery and javascript for client side, and runat="server" posts the data to server. remove runat="server" from head and check.
I am using an combobox with some values and AutoPostBack = true, the page does not refresh.
I have a selectedIndexChanged event as well.
I managed to get the selectedValue and I would like to show this in a TextBox.
In the selectedIndexChanged event I did:
textBox1.Text = selectedValue.ToString();
When I inspect this textbox element with Google Chrome I can see the value is set in the TextBox.
But in the browser the value isn't shown, still an empty TextBox.
Do you guys have any clue why this could happen?
Thanks!
How do you populate items for ComboBox? If dynamically via On-Load event then make sure that method that adds items does not run on PostBack.
Here is your working code buddy.
Don't forget ToString method.

return true;
return false;
}
protected void Foo2(object source, ServerValidateEventArgs args)
{
args.IsValid = this.Foo1(this.MyTextBox.Text);
} // breakpoint
}
}
I set breakpoint in the Foo2 function (comment), but debugger hasn't visited it. I tried writing diffrent text, not writting anything and writting "bar" and pushing enter and tab after that, but it still doesn't work. I mean text changing action. Is it possible?
There's no submit button. You need to add a button to submit the form, which will then trigger page validation.
<asp:Button runat="server" id="myButton" Text="Submit" />
