I have a js function
function(id){
// do a postback here and get the id on the server side
}
I need to send the id to the server, how could I do this?
any way will do, using additional/hidden controls anything
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 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
type="text"
id="addressInput"
onkeydown="inputenter()"
autopostback="false"/>
function inputenter() {
if (event.keyCode == 13) {
seachLocations();
return false;
}
else {
return false;
}
}

When an asynchronous postback happened inside update panel, another postback happens also for MasterPage not only update panel embedded page .
I want to prevent this MasterPage postback .
is this possible ? think like i have a MasterPage
and another page which is test.aspx which is content page of MasterPage
i have update panel at test.aspx
when asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Load
i want to prevent this (it should not also load MasterPage Page_Load)
I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?

iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.
In side the uframe ,button control getting postback the page even the client side method call also.
i tried with the Html button Control also by setting the type="submit" ,iam facing the same problem.
And I got very limited reference about the uframe(codeflex,codeProject).
Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.
On postback, how can I check which control cause postback in Page_Init event.
protected void Page_Init(object sender, EventArgs e)
{
//need to check here which control cause postback?
}
Anyone with similar conclusion? GridView does not databind/refresh upon postback unless the postback is called by itself?
View 1 RepliesOn my page: a Button1, a ListView1, a Panel1 and inside Panel1 an ImageButton1In the ListView1_PreRender-Event the property Panel1.Visible = false or Panel1.Visible = true is set.1. After first loading of the Page Panel.Visible = false ist set in ListView1_PreRender.2. After the postback click on Button1 the criteria for the visibility of Panel1 are evaluated, thus setting in the ListView_PreRender Panel.Visible = true.
View 3 RepliesI have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"
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>

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 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);
I have a page located in an iframe of another page. It calls a js function like this:
function F(a)
{
parent.document.getElementById('A').value = a;[code]....
It results in page reloading. How can I prevent it? Previously I've used return false; and it worked. But not in this case.
I implemented the AsyncFileUpload control on a web page. This web page requires uploaded files to appear in a gridview. The gridview contains the following columns: "File Name", "Confidential" Check Box, and a "Remove" button to remove the uploaded file.
Since the AsyncFileUpload postback does not do a full page postback, I need to "force" a postback on the OnClientUploadComplete event of the AsyncFileUpload control in order to render the gridview after uploading a file. In the OnClientUploadCompleteevent, I use javascript to call __doPostBack. In this postback, I only bind my gridview and display the file information (I don't re-save the file).
The problem: On the AsyncFileUpload's first "partial" postback, the file is successfully uploaded, as expected. On the second postback that I force with __doPostBack, the file is re-uploaded. You can verify this by using Google Chrome, which displays the upload progress. The behaviour is as follows: After selecting the file, the progress increments from 0% to 100% and the file is uploaded. After this, the __doPostBack executes, and you can see the upload progress increment again from 0% to 100%.
How can I make sure the Gridview is properly populated, but that the file is not uploaded twice?
I attached a sample solution which contains the issue:

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:

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?
