I'm having difficulties to find a good explanation and tutorial on how to send an ajax request from one asp.net control (when clicking on an item in its )to update from the server another control.
Is UpdatePanel is the only solution- and does it really avoid a postback?
I'll be thankful for any useful link,
I have a web form, and it appears that when I add the AJAX control toolkit on my webform, my Request.QueryString is clearing out. Here is what happens:
1) User clicks next on form 3, and I load up form 4 (form 3 passes query string to form 4)
2) User clicks next on form 4, and form 4 checks the query string that was passed by 3, and it's emtpy
This only happened when I added AJAX functionality.
I send programatically a request to remote server:
string xml = "SomeXML Data";
string url = @"http://someserver.com";
WebRequest request = WebRequest.Create(url);
request.Method = "Post";
request.ContentType = "text/xml";
//The encoding might have to be chaged based on requirement
UTF8Encoding encoder = new UTF8Encoding();
byte[] data = encoder.GetBytes(xml); //postbody is plain string of xml
request.ContentLength = data.Length;
Stream reqStream = request.GetRequestStream();
reqStream.Write(data, 0, data.Length);
reqStream.Close();
System.Net.WebResponse response = request.GetResponse();
System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream());
string str = reader.ReadToEnd();
but this code throws error:
The remote server returned an error: (401) Unauthorized.
I know user/pass to authorize when IE ask me.
I'm having a problem with telerik RadGrid, I want to enable multiple row selection. I also want to go to the server whenever a row is selected or deselected. I created a javascript function to handle the Grid's client side events (OnRowSelected, and OnRowDeSelected). The functions look like this:
function onOperationRowSelected(sender, eventArgs) {
__doPostBack("<%=myControl.ClientID %>", "rowSelected:" + eventArgs.get_itemIndexHierarchical());
}
The other function is very similar, the only difference is that it sends the string "rowDeselcted" instead of "rowSelected".
On Page_Load I check to see if the request is a Post request using "IsPostBack" and if so, I check to see if it's a rowSelected or rowdeselected.
My problem is when I select a first raw on my grid, a Post request happens (which is expected), however, when I select the second row, a GET request is issued, which (obviously) will result in IsPostBack returning false.
What am I missing here?
I want to know how can we send direct request to .DLL with some parameters. I really don't want to use .ASPX and .ASHX. I hope this .DLL request is used for more secure site.
For example: IRCTC (India Railway site):
[URL]
how we can send or execute page from .DLL in ASP.NET.
I have this wsdl file and here is how the requets look like.

All I need is to send a http post request I pulled from fiddler.
I do not want to use HttpWebRequest class. It makes it hard to set up a request, does not allow to change host,
and when it does send it it looks nothing like the request I want. The server is very sensitive and unless I copy the request headers 100% it will return an empty page. Why can't I just type in the headers and send it that way? What would be 5 minutes of

View 1 RepliesI am dynamically generating controls, and sometimes I want to create a control and have it ignore the viewstate. For example, sometimes the user has clicked a button indicating they want a different form loaded, so the control tree I generate on postback is different from the original control tree. This is fine, except when I call Controls.Add then it tries to load the viewstate form the old controls into the new controls if the control tree structure is similar, and I want them to instead ignore that viewstate(and also ignore the postback values for input controls as well).
Can I do something like set the IDs of the controls or something that would allow me to conditionally prevent them from getting the viewstate/postback data of the previous request?
Edit: If I let the user of the control load the form on demand in postback handler, the postback data is not applied when I call Controls.Add(this really seems like a flaw in ASP.NET, because I would think if you're going to apply viewstate data "after the fact" through Controls.Add, it'd seem you would then apply the postback data automatically as well after the viewstate data is loaded). The real problem I run up against is my control is very dynamic, but the user of my control can't really tell it what to do until their postback handler fires, because one of the things a user can do is select different forms to be loaded via some link buttons. So it's not until the postback handler runs that they know what the uesr requested, and thus can ask my control to load a certain form. So I have to ask them to do convaluted things like saved the formID that identifies the last form to a session variable, and in OnInit they tell my form what the old formID was via a property. My control then loads the form in OnLoad so that it can consume the viewstate and postback data, and later in the programmer's postback handler, they can choose to clear the form and load a different one if they want.
Edit2: FYI Generating IDs for each control unique to the form works great, so I thought I could eliminate the pointless loading of the old form until the programmer requests a form be loaded in his postback handler. But as I mentioned above, what I found was that loading the form after postback data handling has occurred means that data is lost. Whereas viewstate gets loaded via Contorls.Add, playing catch up in the page lifecycle, it seems postback data does not!
Im dynamically generating an HTML Select Box, lets call it myselect. Im creating this select box based on some database values Im generating an HTML Select Box.. almost like a string that Im just spitting out to the page. So it's never a control in the codebehind, just part of a string thats rendered as HTML by the browser. If I submit my form, and in my codebehind I perform:
Dim myVal as String = Request.Form("myselect")
That code will give me the VALUE of the myselect select box. How can I refer to this control to cast it as a System.Web.UI.HtmlControls.HtmlSelect control? Request.Form seems to give me the value, but I want to reference the object itself..
I saw first few video tutorials and they seemed to get the values from the control like text = Textbox1.text; All the form fields are got this way. On the other hand in mvc all the request parameters are populated into a model object. I am not sure whether this already exists or not, but is there any mechanism built-in asp.net which would populate the data from the controls automatically and give us a nice model object which can be saved directly onto the db. Something like this:
<asp:textbox ... ... value="${model.name}">
I don't remember the exact syntax of textbox control. So in this case the textbox would be filled when get request and put into model object when posted back.
While using Ajax in web applications we use XML to transfer the data between server and client. However XSS validation comes into picture, So questions are,1. Is passing XML like this is correct?2. Are we exposed to security issues if we turn off XSS validation?3. Can passing Ajax request with header (content-type = application/xml) solve this problem ?JSON is also good approach to transfer the data but that to invoke XSS.
