How can I access server side functions from the HTML code? See the following code:
<a id="Taggloud" runat="server" class="lblTagCloud" onClick="TagOnCloud_Click">click</a>
Here I'm calling the tagonCloud_click function that's defined in server side(code behind). How can i call that function?
I have a requirement of adding server side variables in client side and other way round. Because I need to set a value from client side using javascript and access the same in code behind page.
I have to use C#.Net and JavaScript.
If I have a standard HTML textbox
[Code]....
but got a readonly error.
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 am applying a field validator on a listbox which works when no item is selected in the textbox and some(most often the submit button) control is made to postback to the server.Now the problem is that if a person has entered the page and want to logout it still gives the same exception messages(which it should) rather than logging out of the page.I am using ASP.NET with c# as back-end.I want the the logout button(rather all except the submit button) to function prior to the validation

View 1 Repliesi 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)
I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.
I have to access my html control and get its value from my server-side code. Is there anybody who could suggest how I could do it?
My html control is very simple: <input type=text>
But the thing is: I can't make it <input type=text runat=server> cause in this case my jquery functionality (datepicker) does not work.
I have an executable file that works fine by hand locally. It converts a file to another new file by some parameters. I'm using ASP.Net and that executable installed win2003 server sp2. I can use it from local but, I can't execute the program from a web browser using system.diagnosting.process. When I use that, I can see the process in task manager with user name "NETWORK SERVICE", and it won't dissappear without ending process by hand and won't work. I tried impersonation, try as a web service, edited local policies, apply all privilages, etc...
View 1 RepliesWhile working through some demos today I managed to trick VS 2008 somehow and I cannot access any server side events or variables in the code editor window. Hopefully
this screenshot will demonstrate exactly what I am missing. No matter what control I pick from my source I get the same drop down items overhead. What is quite weird is that when I drop new server side controls onto the source editor I can set the tag attributes for the events, but when I double click that event there is not an automatic created event handler with the same name created for me. Also, on the property pages there is no events image button (the one with the lightning bolt). The only property page items which have the events image button (lightning bolt) are the ajax toolkit controls. Already tried the "import all settings - VB Default" to blast away everything and no luck..

I want to integrate paypal inside my shopping cart. For that it requires a html form to be embeded inside .aspx page with the action to paypal and method is post.

<input type="submit" value="PayPal" />
</form>
I want to access amount_1 filed.
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".
Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).
What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
I reordered some items in a listbox using Javascript. When I read the items in a postback in the code behind (ASP.NET), the order is in the original order. How do I get the same order as shown in the screen after Javascript manipulation?
