I have an html control (not a server control) like textarea. How can I get the value in this control from the server side when I cause a postback by clicking on a button, without writing the value in the url.
View 3 RepliesI have an aspx page with a bunch of aspx controls, nothing unusual.
In this page I also have an html select control and a simple input control with type="submit". When I hit submit, the request goes back to the server, where I am trying to get hold of the value of the select control, but how can I do that? I tried looking for it in the Request.Form scope, no luck. My code looks like this:
<div id="divSearch_ctl00_ctl01_CustomContent_BasicCustomContent_RoyaltiesGrid1" style="display:none;">
<span>From</span>
<select> [code]....
i use html form and html control to submit data,like bellow:

iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.

//need to check here which control cause postback?
}
I am realizing a table with multiple rows for a Sharepoint webpart.
In this project, I would like to have a new html control which contain a LinkHtml in one column and another label in another column.
Essentially this html control would be a row used for my html table.
At the moment i am doing a row like this in the main class :

I have a report that I generate with HTML.
I'd like to get the HTML output of the page, and be able to send it via email. I'm having problem with session, because the report redirect me to the login page because when I create a new WebRequest, it doesn't use the information of the current session.
Is there a way to get the HTML of the report without having to code a work-around for the security ?
I have a literal control in markup. I am generating html layout in C# and then set the text property of literal to the html.
StringBuilder sb = new StringBuilder()
sb.Append("my html.....");
lt.Tex = sb.ToString();
Some of these html elements need to post back and call a function on the server side. I googled and found a couple of posts using __doPotsBack, but it is not working. Below is how I am adding an image and adding onclick script.
sb.Append(string.Format("<img title="Add" src="images/Add.gif" onclick="javascript:__doPostBack('Add','');return false;"/> "));
It does cause postback, but Add function is not called. Additionally I want to pass some parameters to Add function.
I am currently working on a ASP.net web app which the user enters info into input boxes and selects items from dropdowns. Once the user is finished they click on a button which validates the fields (using jquery validate plugin) and then removes the fields and replaces them with only field value. So essentially there are no more input fields only text.
The next step is to click on a button which will convert the html to pdf. However, when I do this, the PDF that is generated has all of the input fields that I previously removed. When I debug, I notice the HTML being returned is still the old HTML and when I view the page source, I am still seeing the old HTML even though the browser is showing the changes.
I am using this to grab the current html after the button click:
string htmlCode;
WebClient wb =
new
WebClient();
htmlCode = wb.DownloadString(devurl);
if (Page.IsPostBack)
{
//here I need to know which control causes the postback
}
I would like to ask how can i make an html anchor (a element) or even any object to do a postback or to execute an server side method?I want to create a custom button (a wrapped with some divs to do some custom them) and i want to implement OnClick to be look like the ASP.NET LinkButton?Like<a href="#" onclick="RunServerSideMethod()">Just a simple link button</a>

View 1 RepliesI am using Javascript to create dynamic controls on the page I am not dealing with File Uploads, just creating custom field things.
I think I need to override SaveViewState and LoadViewState events to keep my controls in the ViewState.
how to make a cell in an html table, like "cellMonday" below, clickable so it can do a postback, if possible.

I have an input box that I don't want postback to occur on someone striking the enter key
I want the javascript event to take place instead.
<input

function inputenter() {

seachLocations();

i've a contact form that's plain html and an asp.net button to post everything to server side (and eventually validate).
the problem is that if server-side validation fails, input-values are not manteined.
what's the best client side to mantein fields value?
this is my actual jquery code, i use css selectors:
<script>
$("form").submit(function() {
var asapReqStr = "???";
var asapTmp = $(".asapRequired").val();

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.
So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.
How to do this? Or any better way all together on the copy-chart issue?
I add HTML and tags to Page dynamically. But after every postbost, all values are empty. What can I do for Solve?
View 2 RepliesI have a simple page containing a GridView control that generates thead and tbody tags after rendering. In my jQuery script, I have a line that reads this way:
$('#GridView1
thead').eq(0).html()
When the page loads for the first time, this script returns an objects and works well. But when I click a button and cause a postback, it returns null. By the way, the button changes the number of the rows returned from the data source (based on the value of a textbox) and updates the grid.
I have an iframe in .aspx page , in which i open an html page(local) and I want to postback my .aspx page when user click on an img( that is in html page ) and get that image id on server side.
MyAspxPage -> Iframe -> HtmlPage -> img
I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.
I don't want to do it using JavaScript/jQuery but instead do it at server side.
A JavaScript workaround that implements it can be found at this link. [URL]
Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.
This is the reason why I need a way to find out the HTML of the page causing the PostBack.
I'm reading an invoice dataset and building a html table with checkboxes and textboxes in it, and I put that code in a postback = false block, then i got a button and a literal. The button click will loop through the html table checkboxes to calculate a total and assign it to the literal and display it. I got everything working except one thing, every time i click the button, the html table refreshes and lost all the value in textboxes....even though I put the html building block in the postback = false block,it seems like it still won't preserve the values in the textboxes once there's a button click...Anybody knows a solution to that? I want the textboxes keep what values are there.
Here is the code part:

When I click the button to open the modal popup it shows the popup but then continues and forces a postback causing the page to reload and the modal popup to be hidden again.Here is the markup for the control:
<asp:Button id="LoginOpenButton" runat="server" Text="Login"/>
<asp:Panel ID="ContentPanel" runat="server" CssClass="modalPopup">
<fieldset> [code]....
My script manager has no properties other than the id and runat set.
In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
