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 code in dropdownlist_selectedindex change like this
i want a confirm box from server side code but it's not working
a= a+", "+texbox1.text;
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "confirm", "<script>return confirm('"+a+"'File Already Exists do you want to replace!');</script>");
i have a <div> named 'mydiv' on a web page and have set it's runat property as <server> so it is visible within
my vb.net server side code.
i can see the mydiv within the server side code.
my question:
how do i adjust the height/style of the <div> withion the vb.net code so that whe the page is posted back the new height/style settings apply. how do i get to the style properties server side?
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">
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 am working on page where data will update in every 10 second by scraping data from other Stock website. So basically page is displaying stock data which update in every 10 seconds. I am using update panel and timer control. Now problem is that if 100 users open the webpage 100 request go server in each 10 seconds. I want to implement Cache on page where Cache version of page serves to other user. I am using <%@ OutputCache Duration="10" VaryByControl="Timer1" %> but when event occur code run intends of delivering Cache version of page. What I am doing for test.
1) Open page in different browser in local
2) Checking browser type using code
Dim s As String = "" With Request.Browser s &= "IP = " & HttpContext.Current.Request.UserHostAddress & vbCrLf s &= "Browser Name = " & .Browser & vbCrLf End With Label1.Text = s
if page first open in IE then if I again open in firefox it shows browser type IE but after 10 sec interval it will update type to firefox. So I want to display Cache data only instead of executing server side code for each different browser.
i want make html table in format so i used follwing code but it just print tags(rather than analyze them as html and give appropriate output )
[Code]....
Output got when tried to use TransList.ToString() output got was <html> <head> </head><body><table><tr><td>1</td><td>11/24/2010 12:00:00 AM</td><td>Paypal</td><td>30</td></tr><tr><td>2</td><td>11/24/2010 12:00:00 AM</td><td>Paypal</td><td>300</td></tr><tr><td>3</td><td>12/10/2010 12:00:00 AM</td><td>Paypal</td><td>240</td></tr></table></body></html>
I open a popup window by client code. Now I want to do some calculation on this popup window & if it success then I want to save the calculation result in a session variable and close the window. I mean I want to click a button on popup window, it will do some calculation on server side and if it success the it will store the calculation result in a session variable and close the popup window.
I am running some custom code in a user control using the <%=Code%> tag. The problem is that the code seems to run before the PreRender event. Is there any way for met to get this code to run after the PreRender event?
I have a user control with a dozen radion buttons in it.Every pair of radio buttons execute a Sub on server side.All of the radio buttons have the autopostback set to true.There is a public Sub of the usercontrol that gets called only once by the page and loads the data setting the radio buttons to checked or not checked.The problem is, that once a radio button is set, it will execute it's server side code on every postback even if the postback is caused by another control on the usercontrol or even another control on the page. So if all the radiobutton pairs are set and a postback is caused, there will be six server side Sub executing! Casting the sender in each of those Subs gives back the radiobutton that is checked at that point, so it's if on every postback the event is fired for each checked radiobutton.
I'm building an application that creates bar code images based on the number of selected rows in a GridView. It counts out 6 bar codes and the corresponding labels, and then it needs to force a page break when my counter hits "6".
How do you force a page break from your server side (VB page-behind) code in ASP.NET?
Can you change the pagestyle from the code-behind? I wanted to try : "pagestyle = "page-break-before:always" - but it was not an option in the intelisense menu...
I have a series of textboxes on a FormView. There is a textbox for entering a percent for a deposit amount and next to that a corresponding textbox for entering a dollar value for a deposit amount. There are 3 sets of these.
If a user changes a percent textbox, I update the dollar value textbox based on the percent times the project's total cost. If a user changes the dollar value textbox, the percent textbox gets updated as a percent of that dollar amount divided by the project's total cost.
I have the percent textboxes formatted as "{0:0%}" and the dollar value textboxes as "{0:C}".
When a user types into the textbox, the formatting goes away and we get raw numbers but I don't want those raw numbers to remain as such after they tab or click out of the field. I added a TextChanged event to reset the formatting. This works fine on reformatting the percent textbox but the currency one remains as just a raw numeric value.
Here is the markup (ignore the lack of validation for numeric input only...it will be added):
I've looked at replacing the ImageButton web control with a simpler HTML img tag (which is what the PopBox documentation suggests). Yet, I don't know how to populate an <img> tag from the CodeBehind file. Here is a typical statement which sets the .SRC property from an ASP.Net dataset row:
Visual Studio 2008 does not complain about this declaration above but in the codebehind file, how would I address this so I could populate the .Src attribute.
Intellisense, cannot even "see" this Me.imgPicture.src = theUrl 'this won't compile...
I added this at the top of the codebehind but seemed to have no effect:
