I have a website that shows images people have uploaded.

I want to be able to show a popup window when i move the cursor over an image. It should show information about the user that i take from the database.
I have found a javascript that works, it fades a window in and out. But i cant call it from codebehind.
My default.aspx has this code:

I have a script written in PHP that does a number of things. I do not want to have to rewrite this in ASP.NET. I wanted to know if anyone knew how I can just call the PHP file from the code behind page after a button is clicked.
I cannot use javascript because things need to be added to the database and need to be successful in the function before I can call this php file. I do not need any of the php code to show up, I just need the php file to run and I need to add a parameter to the end of the URL.
I have a Java Script method that is called from an Aspx page named Default.aspx. The Java Script method is calledwhen a linked button on that page is pressed.
function Redir()
{
window.status="";
va urlGetit = "ConvertToExcel.aspx?" + "&test=" + 7;
xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET",urlGetit,true)
}
This Java Script method then calls my Code behind file named ConvertToExcel.aspx.cs" where I build an MS Excel file
I'm trying to dynamically load an image from my code behind file, however I want to be able to resize the image thus reducing the file size sent to the client. I've come across a few samples but without much luck. So far I have the following:

Precisely and concisely, I have aspx page that has only one button "Generate". If the user clicked on this button, one HTML page should be created.
The created HTML page should have title "Home" and the Body should contain "Hello World".
1) What is the code that should be written inside "Generate" button in order to accomplish this functionality?
2) Assuming the HTML page gets created, How to store it inside specific folder on the local drive? Or how to store it inside DB?
<configuration>
<system.net>
<mailSettings>
<smtp
from="user@user.com">
<network
host="smtp.server.com"
password="password"
userName="username" />
</smtp>
</mailSettings>
</system.net>
</configuration>
How can I call the "host"setting from the App.config file in my C# code?
I have tried this but it does not work.
SmtpClient mailClient =
new SmtpClient(ConfigurationManager.AppSettings["network"]);
I have this in my code-behind file (VB.NET):
[Code]....
Here is the HTML source of the part of the page:

Where that comment in the code-behind file says "REFERENCE IN CODE HERE", that is where I want to set the value of the "remLen3" input (client-side control) to "30 characters left."I obviously left out irrelevant things like inserting the txtNewComment.Text into the database. But what's going on here is when the user types in something into the txtNewComment text box, I'm using javascript to change the value of the remLen3 control.My problem is that when I submit the text from the txtNewComment textbox to the database and set the txtNewComment.Text equal to Nothing, I don't know how to reset the remLen3 field value back to saying "30 characters left.". I already tried to add a "runat="server"tag to it, but when typing stuff into my txtNewComment textbox it gives me an error. I already tried to figure out what the error meant, so I'm not going to spend time trying to solve it anymore; I would rather just see if there is a workaround to using the runat="server" tag. Maybe do some kind of a CType(FETCH_REM_LEM3_HERE_SOMEHOW, INPUT_TEXT_TYPE??).value = "30 characters left". If there is a way of converting the input text control (remLen3) that way, then how would that be done? I just want to change the value of that field when the server-side button is pushed.
I want to call a function present in code behind from front page (html : source code)
i want to use like this:
Source code
<a href='<%# linkAlpha("B").ToString()) %>' title="B" id="B_List" runat = "server">B</a>
Code Behind
protected string linkAlpha(string value)
{
// /market-research/<%#Eval("customname")%>/
string str = "";
if (Request.Url.DnsSafeHost == "localhost")
{ // /market-reports/<%# Eval("customname")%>/
str = "Alpha_Category.aspx?q=" + value.ToString().Trim();
// Response.Redirect("Alpha_Category.aspx?q=" + value.ToString().Trim());
}
else
{
// str = "/market-reports/" + value.ToString().Trim() + "/";
str = "/Alpha_Category.aspx?q=" + value.ToString().Trim();
}
return str;
}
how do you call code behind button click event or a code behind method
from javascript.
I have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
View 2 RepliesI have a webservice I need to call via a link. The webservice returns a pdf document and takes a document Id as a input parameter.Under normal circumstances I could have the link call some code in the code behind which in turn calls the webservice.
However the difficult part about it is I can't add code to the code behind. The reason is it is for some CMS users who want to know what links to add to the page which will download the pdfs. I can only add the link to the aspx page.
I'm a bit new to .net so i was wondering if a thing like this is possible. I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.
View 2 RepliesI am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Public Class CustomValidate
Inherits System.Web.Services.WebService
'ACCESS VIA JSON
<System.Web.Services.WebMethod()> _
Public Shared Function AJAX_Test(ByVal date1) As Boolean...
Return True
End Function
End Class
Javascript: JQuery JSON
function isDates(source, arguments) {
var isValidDate;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CustomValidate.asmx/AJAX_Test",
data: '{date1: "' + arguments.Value + '"}',
dataType: "json",
async: false,
success: function(result) {
isValidDate = result;
},
error: function(httpRequest, textStatus, errorThrown) {
alert("status=" + textStatus + ",error=" + errorThrown);
}
});
arguments.IsValid = isValidDate;
}
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
ringht now i am working with one web page, in that page i have 3 sections of data [or 3 set of data] in 1 set 4 to 5 fields actions to be taken when we click on save button 1st it should save the 1st fields data in one of my sp and it should get the table level id it should loop that table level id into another set of records & insert into to the another sp
View 4 RepliesI am creating a html table dynamically with some content and along with that want to add asp.net textbox control under one of its row. I am adding the control as
<tr> <td><div>Text :</div></td><td> <asp:TextBox ID='txtNoOfLicences_'"+j.ToString()+ "runat='server' Width='81px' OnTextChanged='txttext_TextChanged' AutoPostBack=true MaxLength='4'>1</asp:TextBox><asp:Button ID='btnTotal_'"+j.ToString()+" runat='server'
Text='Go' OnClick='btnTotal_Click' /></td></tr>
I want to call the OnTextChanged event of a static control added on aspx page.But the textbox is not getting displayed.Similarly I want to add a asp.net button also but it is also not visible.
I have a page that contains a custom tab control. When you click different tabs, it does a an ajax callback. During that ajax call, the code dynamically loads a different control based on which tab was clicked, then adds it to the appropriate tab. So basically I have some code that does a switch statement, uses LoadControl(), then adds the control in.
The issue I'm having is that none of the javascript within each of those controls that gets loaded is getting registered on the page. Based on this thread:
[URL]
I thought I just had to switch from using Page.ClientScript.RegisterClientScriptBlock to ScriptManager.RegisterClientScriptBlock. I did that, but still nothing. Am I misunderstanding something about the ScriptManager? I want the javascript to be registered from within the dynamically loaded control, which happens to be loaded during an AJAX call.
how to call code behind from javascript without postback ?
View 7 RepliesMe with C# asp.net I am displaying a pop up window using javascript in the page load like
<body onload ="Popup.showModal('modal')">
I want to call this popup in the code behind
protected void Page_Load(object sender, EventArgs e)
{
want to call it here
}
I have the following entries in the css file.
a.intervalLinks { font-size:11px; font-weight:normal; color:#003399; text-decoration:underline; margin:0px 16px 0px 0px; }
a.intervalLinks:link { text-decoration:underline; }
a.intervalLinks:hover { text-decoration:none; }
a.intervalLinks:visited { text-decoration:underline; }
a.selectedIntervalLink { font-size:12px; font-weight:bold; color:#003399; text-decoration:none; margin:0px 16px 0px 0px; }
a.intervalLinks:active { text-decoration:underline; font-size:large ; }
Edited for trial:
a.big-link:link{}
a.big-link:visited {}
a.big-link:hover{}
a.big-link:active{font-size:1em;}
Whenever i take the click on some links (not shown) which is embedded in the webpage ..i can see the change in the link
a.intervalLinks:active { text-decoration:underline; font-size:large ;
(the font of the link will become large)
but after clicking the page refreshes ..the changes will go away
i want to keep the change for ever in that link ...even there is a page refresh
i understood that ..this can achieved only throughg the code behind of asp.net
Following code should work:but unfortunately its not
protected override void OnInit(EventArgs e)
{
rptDeptList.ItemDataBound += new RepeaterItemEventHandler(rptDeptList_ItemDataBound);
}
void rptDeptList_ItemDataBound(object sender, RepeaterItemEventArgs e)

I am just learning ASP.Net and i am more using C# as code behind than vb.I am trying to call a method of the code behind (file.aspx.cs) from the (file.aspx).I know how to do it the easy way:- create a button from ASP.Net and double click on it than the property "onclick" will be linked to the method.But i don't know how to do it from a query:
- By example, from an Access database,i use the syste, [using System.Data.OleDb;] and i made a query and display it into a standar object named "Table" which has rows (tablerow) and cells (tablecell) and the cells have one of their properties which is "Controls" where developers can add button (regular button, image button, link button, etc). With i display the buttons from the database, i can not call a method from code behind! I can't either use their properties "onclick" to call i method i created in the code behind.Is there a way to do it ?
Using "Page.ClientScript" how would I call the function from code behind?
Code:
<script type="JavaScript">
function OnBeginRequest(sender, args)
{
$get("IMGDIV").style.display="";
}
</script>
i have a textbox,when i type some thing on the textbox and click on the Enter key.I need to call a particular function in Cs code.How it possible.
