View 1 Replies If I have a web form with a button control on it. Is their a way to have it's button press method called from a Java Script method?

I am maintaining a website that has .Aspx web pages with no code behind C# files. This has been a challenge for me, because I need to do the following:
1.) When the page first loads, display a Java Script popup message box.
So how can I do this if I don not have a code behind C# file where I can check for isPostback in the on page load method? Can the on page load method be placed inline in the .aspx code? Anyway I need to figure out how to answer my question 1 above.
I need one common rounding function in asp.net and I will use that function in Java script, Code behind (.vb file) and SQL server (Stored Procedure). Is there any possible solutions in this requirement?
View 2 RepliesI want to test this code found here. It allows me to auto-load content from server as the user scrolls down the scroll down. I am having difficulties trying to convert code to C#/ASP.NET. Primarily, I want this code to be translated to C#/ASP.NET:
package com.vraa.demo;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class InfinitContentServlet extends HttpServlet {
private static Integer counter = 1;
protected void processRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
try {
String resp = "";
for (int i = 1; i <= 10; i++) {
resp += "<p><span>"
+ counter++
+ "</span> This is the dynamic content served freshly from server</p>";
}
out.write(resp);
} finally {
out.close();
}
}
@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
@Override
protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
}
In addition, I would like to know if I have to make any changes to this JavaScript code:
<script type="text/javascript">
$(document).ready(function(){
$contentLoadTriggered = false;
$("#content-box").scroll(function(){
if($("#content-box").scrollTop() >= ($("#content-wrapper").height() - $("#content-box").height()) && $contentLoadTriggered == false)
{
$contentLoadTriggered = true;
$.get("infinitContentServlet", function(data){
$("#content-wrapper").append(data);
$contentLoadTriggered = false;
});
}
});
});
</script>
I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added. Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?

In a Web server is running. NET Framework 4.0. Whatever the methods and technologies you would advise me. applications built on the basis Asp.NET MVC 2.
I have a database table in MS SQL Server. For each table in database, I must implement the interface for viewing, editing, and deleting. So code generator must generate model, controller and views.. Generation should happen after clicking on the button in WEB UI.as Model I use .NET Entity Framework.
Now, I need to generate controllers and views.
So if i have a table with name tableN1. and below its colums:
[ID] [bigint] IDENTITY(1,1) NOT NULL,
[name] [nvarchar 20] NOT NULL,
[fullName] [nvarchar 50] NOT NULL,
[age] [int] NOT NULL
[active] [bit] NULL
agree: if the type bit, then generate a checkbox.
nvarchar (20) - textbox
nvarchar (max)-textarea and so on.
for this table, i want to generate views and controller.

View 1 RepliesIs there a way to implement a logic for validatorcalloutextender for the code below?
This code sample is a part of button click event.
[Code]....
Inside my boxLang_OnSelectedIndexChanged() event I got this :-
if (txtbox1.Text != "" && txtbox2.Text != "")
{
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirm", "confirm('Changing the language will clear the text in the textboxes. Click OK to proceed.');", true);
txtbox1.Text = "";
txtbox2.Text = "";
}
Now what is happening is that. When I select a different item from the drop down list this confirm box does show up BUT it first clears the content of the text boxes and then this confirm box appears. What I want is that the textboxes content should be cleared ONLY when OK is clicked.

I have found all kinds of tutorials on the web showing how to implement the AJAX slideshow extender, but can't get them to work. All I want to do is put a simple slideshow on a master page. I want to use a code behind file for the c# (do not want the script on the page itself.
I ran into a couple of problems with the samples on the web. Specifically when I try to add System.Web.Services.WebMethod and System.Web.Script.Services.ScriptMethod - VS 2010 doesn't know what the "WebMethod" or the "ScriptMethod" are. Further, VS2010 express keeps telling me "{" expected - on the line AjaxControlToolkit.Slide[] slides = new AjaxControlToolkit.Slide[5];
Every tutorial on the web seems to be for ASP.net 2.0 - and is at least 2 years old. Is there an easier way in ASP.Net 4 to implement the slideshow control? I am new to c# in general, so if someone could provide a simple cs codebehind file - and the code on the aspx page, that would be great. I understand more than I can write.

how to generate HTML code from the code behind?
I would like to build a form that generate an html code inside a for loop.
I will let the user enter the photo name and No. of photos
Then I will generate an HTML code like this:
<a href="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(1).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" target="_blank">
<img src="http://www.mzinj.org/images/gallery/Photo%20(2).jpg" alt="" width="345" height="247" /> </a> <br /> <a href="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" target="_blank"> <img src="http://www.mzinj.org/images/gallery/Photo%20(3).jpg" alt=""
width="345" height="247" /> </a> <br />
depending on the No. of the photos the code will be duplicated in the loop
Then I will display the result of the loop in label or in a textarea to let the user copy it any where
The problem is that while compiling my code it considers the HTML code as a part of the behind file and gives errors on the single quote, the double quote and on the parentheses
I have been asked to support a legacy app and I can't get access to the code behind files. I need to add a new feature that gets a list of items from the database on page_load, what way would adding an "in-page" page_load affect the compiled page_load?

When the user hits the Enter Key I want to go through and validate some fields and kick it back to the user if a fields doesnt' validate. With the above code, the btnEnter_Click still is getting called even though I have it to return. I tried return false; too incase I misunderstood something.BTW, yes the code is falling into the Else Statement when stepping through code.
