I have a button where I use an Animation Extender. When I click the button I have to set OnClientClick="return false;" otherwise the Animation Extender closes.
So that causes my problem. How do I execute server side code from this button?
I have tried this code in my code behind, but there is an error:
Code:
Dim strScript As String
strScript = "<script>"
strScript = strScript & "return false;"
strScript = strScript & "</script>"
ScriptManager.RegisterStartupScript(Me, GetType(Page), "MyScript", strScript, False)
This is my code for the Animation Extender:
Open data"></asp:Button>
i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click.
using : asp.net web form
i have a web form with few textbox and a gridview control and a button.
if i click on the button i am executing two things
1) asynchronously get data from server to client (working great) and able to display the data in the textboxes.
2) same click i want to bind the gridview.
[Code]....
recap:
1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.
PROBLEM:
if i have onClientClick="return LoadDataById(); then it executes ONLY ajax code and does not execute server side but if have onClientClick="LoadDataById(); then it executes client and server but textbox value wipeout. (the textbox value popuplate through ajax)
When a user clicks a button I need to create a .bmp file on the server. After the .bmp file is created I will load it into the html page. Would Ajax be the best way to accomplish this?
Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
In my asp.net website I am creating a session upon user login and I would like to perform some operations in the database just before this session will expire.I am having problem in determining where should I write code and how will I know the session is going to expire.
I am not sure if 'session_end' event of 'Global.asax' suits my requirements as the session I want to check is created manually(not a browser instance).
How can I trigger a jQuery function with the Gridview Select button? I want that the select button trigger the jquery function that has the row details (it's already working with a asp:buttonfield ), and select the row so i can get the values and send it trough e-mail with another button. I don't know if this is possible. or, Can I trigger the jQuery function from code behind with the select button Sub? How?
[Code]....
This function capture the gridview cell values that are hidden and show them in a div outside the gridview (it works as row details). I have no problem with this.
[Code]....
All i need is a button that select the row index and/or values and trigger the jquery function . Or I can execute the jQuery function from server side. I don't know if it's posible.
I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
I'm not sure if this is an easy issue to solve, but I can't seem to figure it out. I have a ModalPopupExtender (obviously) for a panel that contains a two labels, two textboxes, and two buttons (Ok and Cancel). What I would like to do is when the Ok button is clicked, the page post back and the server click event execute (along with normal page events). When I try adding "__doPostBack("ModalOk", "");" as the OnOkScript, the page posts back, but the click event doesn't execute. (the click event is Protected Sub ModalOk_Click(blah blah) Handles ModalOk.Click).
The only way I got it to work (which is fine with me, I just thought I'd ask why it isn't working normally) is by checking to see if the Request.Form("__EVENTTARGET") is equal to "ModalOk". If it is, then I call the ModalOk_Click() sub. Like I said, this is fine with me, but it should be able to be avoided. If the __EVENTTARGET is equal to "ModalOk", then the "Handles ModalOk.Click" event should automatically be called, shouldn't it? Following with the general problem here, how does the server determine which events (other than the page events) to execute (or at least which button.click event)? I understand that the __EVENTTARGET supplies what causes the postback, but if a button is clicked then __EVENTTARGET is not set. So then does the page check the Request.Form for a button? Or is it more complex/simple than what I'm asking?
I have a web app that needs to do two things at the same time. After a user clicks a button on the site, a javascript function needs to execute and while thats working I need the server side code for the button click to execute without waiting on the client side to finish.
To be more specific, the client side function takes about 23 seconds to complete, and while that is running the server side code promts the user for printing a document. So I need the javascript to run "in the background".
Is it possible to execute two or more client side functions with a single button click? (I have written 3 functions in my .aspx page and need to validate on client side)
send me sample code with 3 client side functions using single button click.
I have a gridview that displays items awaiting supervisor approval. The supervisor clicks the Review button and a modal window should popup with the results of a database query on the record. I am using a dataketname param on the grid. Here are the ASPX elements, The gridview and the modalpopup code
[Code]....
I am using mpeApproval.Show() in the codebehind but it isn't firing. I've been at this literally all day and am feeling pretty stupid at the moment. Have I provided enough for you to make a determination?
The text and style runs properly but the server side code is ignored. How would I write this so that it's not ignored? Do I have any options?
Text = Text.Replace("Blank Div", "<div class=""New""><% If Session(""User"") Is Nothing Then%><asp:LinkButton ID=""lbtnSignup"" runat=""server"">Sign up</asp:LinkButton><% End If%></div>")
I have an ASP.NET (3.5) web page which calls a few web methods (SOAP based) using jQuery's .ajax method. The web methods implement 'ScriptMethod' attribute and return JSON data. The web service file (asmx) is local to the same project.
I noticed these web methods execute synchronously on the server which means they run sequentially and affect performance negatively, some methods are waiting, when some of them are slow.
I read this article and I am not sure if I understand that WebMethods which implement Scriptmethod can run synchronously only (they implement IHttpHandler not IHttpAsyncHandler).
If this is true, I might have to change the design. I am looking for other designs, maybe like using WCF, where the browser can call webmethods using JavaScript and the web methods run asynchronously on the server.
In my application, I have one Gridview on click button of one of the column I show Modal popup Extender. In Popup window I display another GridView with paging. And also I want to do operations such as Update, Delete and Add. As all these are Link buttons none of the event associated with them are firing.
Is there any way to execute server side events on Modal Popup Extender.
I have a modalpopup with save button.. I gave some function in that button click.. But it is not working i mean the button click is not going to those codes. How can i make those code execute when clicking the button..
in a form i have a buttoin, when click both OnclientClick and postback should happen. on clicking the "Email" button a client side "mailto" tag should do the work and pull a new message window on the client's machine.
whereas, the email addresses should be invoked by the post back. so , when clicking the button the server side post should happen and on return the client side script should be invokded with the values read during post back, and populate all the email addresses.
i need know how to first do a server hit take the values and then execute the client script with those values without using AJAX
If I have a standard HTML textbox: I can retrieve the value using Request.Form. But how do I go about populating this textbox from the server-side? I tried Request.Form["txtTest"] = "blah"; but got a readonly error.
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.
I'm wanting to insert some javascript in the body of a page using ClientScript.Register..() when a user returns to it (either by back button or on link click). When I use the back button the inline server script is never hit in debug. Any way to get the server to evaluate the code every single time the user is directed to that page.
I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?
I have read alots of articles from fourms such as belowhttp://forums.asp.net/t/1346690.aspxhttp://forums.asp.net/t/1489818.aspxhttp://forums.asp.net/p/1426153/3189859.aspx#3189859
I am looking through a sql stored procedure which I might need to update in the near future. Basically the stored procedure is about 20 lines long. The stored procedure first builds a query
and stores it in a variable named "@Sql". And then for the last two lines of the stored procedure it appears that the big sql statement stored in "@Sql" is executed by using the "EXEC" command. See below. What is confusing though is that the query appears to be exectuted twice? Why was the query written in this way. Don't both lines do the same thing? Why is it being done twice? Could this possibly be a mistake on the part of the person who wrote the query. Below are the two lines I am talking about?
