Usercontrol Not Posting Data?
Jan 13, 2011
I have a simple Usercontrol that has an image and textbox. This has just been really difficult to use, and I am wondering what I am doing wrong.
[Code]....
The first problem is the in the Page_Load procedure. It seems that if I create this control dynamically, the Page_Load is called before the image or textbox are created making it impossible to intiantiate the objects. Since this was so difficult, I just created 5 of these usercontrol and put them on the page.
[Code]....
I can now set the image src from my code, but when I click submit, there is no information about the textbox contents (as well as the image contents). The information shows in the browser, but it is not returned to the server code behind section of my code.
[Code]....

I am posting data to an external website server side. This works when the data parameter is less than about 640 characters. The data gets truncated beyond around 640 characters. The code I'm using is below:
Function PostData(TransId As String, QuoteNumber As String, data As String) As String
Dim url As String = "http://localhost:49608/test2.aspx"
Dim encoding As New ASCIIEncoding()
Dim request As WebRequest = WebRequest.Create(url)
request.Method = "POST"
Dim postData As String = "WAA_PACKAGE=Vendor&WAA_FORM=blahblaj&WAA_HTML3CLASS=nHTML&VendorID=ENG3135&"

I have a some problem while Posting xml data Using HttpWebRequest. Actually I want to Post 3 Form variables
2 of them are for credential and the third one is for XML data to an api, The api will authenticate and will process the xml data, and will return success if no error found.
Here is what there documentation says.
The data will be passed to the gateway via an HTTPS FORM post and a string value of "success" will be returned upon successful receipt of the data. Three total FORM variables will be posted, two of which will contain credentials, and the third will contain the HR-XML data. A string value of "error" will be returned if the posting fails for any reason.
Form Fields integration_field1 = 1234, integration_field2=2345pwd, hrxml=form field containing the HR-XML order (string)
Here is what I have Coded..

I have an aspx page like this:
[Code]....
Well, as you see clicking the button will redirect user to "http://www.somesite.com/somewhere" and also will post three specified fields as data to that page; which can be retrieved using Request.Form["field#"] at destination.
I want to do all these works using C# or VB.NET code, because I don't want my hidden fields to be accessible to users (who may use firebug or something similar).

I am using asp.net mvc 1.0. In this I have to create an UI for modifying the profile of the user. Now this modfiy profile will contain jquery tabs. and each jqeury tab will show some results such as user's personel information, professional info, etc on seperate tabs. I also want to give user ability to modify the fields and save this modified data. I am just not getting any idea how to do that. I have searched on internet for various jquery examples. most of them are just showing data to user by creating some partial views. Also i am not getting exactly how this functionality can be achieved through ajax on click of button.

Since we can't post data to cross domains, I want to post the data to my aspx page and a code-behind code will take the data and submit to cross domain (which is not being operated by me, so I don't have permission to modify source code for jsonp) and also the website to which I pass my post data is also returning a cookie which includes shopping cart info and I need to store it on my local browser cache as well.
What I know is I need to use WebResponse and WebRequest classes for that manner.

I have a Person class with an Address property. The Address contains a Country property of type Country which in turn has a CountryCode property of type string, as follows:
Person.Address.Country.CountryCode
I have a select element on the page with a name of "Country.CountryCode". With MVC 1 this was bound perfectly to the CountryCode property of Country. In MVC 2 however, I get the following error when the page is posted back:

I have an application that needs to post data to a url on the web and then receive an xml response. I have an HTML form (provided by vendor) that posts the data correctly, however when clicking the submit button the page is redirected to the post url and the xml is displayed in the browser. I need to do this on a postback within an existing asp.net project. Basically, the user will fill out the form, the form data will post to the url, the xml response will be received, and the appropriate values will be displayed on the screen. I've found a bunch of examples for doing this but I just can't seem to get my head around it. Can anyone point me in the right direction or explain how I should go about this?

I am using the code as below of this post:First i will an fill array variable with the correct values for the controller action.Using the code below i think it should be very straigtforward by just adding the following line to the javascript:
data["__RequestVerificationToken"] = $('[name=__RequestVerificationToken]').val();
The <%= Html.AntiForgeryToken() %> is at his right place and the action has a [ValidateAntiForgeryToken]
But my controller action keeps saying: "Invalid forgery token"

Type","Phone","Type","DOB "," 7:30
[snip]
The only things I need from this are:
Patients Name
Drs Name
Patients Phone Number
Appt Time
Appt Date
and the rest of the information I can discard. A customer uploads this as a .csv file (even though it really isn't as you can see) and I'd like to parse the needed information and post that to my SQL database and discard the rest. I think I can do this with a dataset but I've never built that before. The fields from the customer will always be the same and the fields I will need will always be the same. Also, the date time has to be in the format of yyyy/mm/dd:hhmm and the phone number always has to have 512 as a prefix. Here is the code I currently have for my site:

In my ASP.NET MVC 2 web application, I allow users to create custom input fields of different data types to extend our basic input form. While tricky, building the input form from a collection of custom fields is straight-forward enough.However, I'm now to the point where I want to handle the posting of this form and I'm not certain what the best way to handle this would be. Normally, we'd use strongly-typed input models that get bound from the various statically-typed inputs available on the form. However, I'm at a loss for how to do this with a variable number of input fields that represent different data types.A representative input form might look something like:
My date field: [ date time input
control ]
My text field: [ text input
field ]
My file field: [ file upload
control ]
My number field: [ numerical input control ]
My text field 2: [text input field ]
etc...
Ideas I've thought about are:Sending everything as strings (except for the file inputs, which would need to be handled specially).Using a model with an "object" property and attempting to bind to that (if this is even possible).Sending a json request to my controller with the data encoded properly and attempting to parse that.Manually processing the form collection in my controller post action - certainly an option, but I'd love to avoid this.Has anyone tackled an issue like this before? If so, how did you solve it?Update:My "base" form is handled on another input area all together, so a solution doesn't need to account for any sort of inheritence magic for this. I'm just interested in handling the custom fields on this interface, not my "base" ones.Update 2:Thank you to ARM and smartcaveman; both of you provided good guidance for how this could be done. I will update this question with my final solution once its been implemented.

I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.

I have view that dynamically adds multiple partial views with a foreach statement with the standard <%Html.RenderPartial("partialName", model); %> . The partial view control has just a label and textbox control. When I view the source html generated it correctly has a single form control around all the multiple labels and textboxes. My single submit button, inside the form though does not send any of the form data back to the controller though when using FormCollection.

I have a Datalist with 6 elements inside (Labels and Hyperlink)This is in the "results.aspx" page. The process in started by the query stings being sent to the this page:...results.aspx?q=(ItemNameSeached)&cid=(City ID number)I have this bound to an SQL Data Source. My problem is that the ITEM_NAME, ITEM_ID (for the More... link), and the ITEM_BUILDING_ID are in one table in my database; The BUILDING_NAME and BUILDING_ADDRESS are in another table.I have an sql query string working to get the information in the items table but I don't know how to get the Building Information which is on another table. I know the sql query to get the building information (SELECT building_Name, building_address FROM buildings WHERE building_id = @ITEM_BUILDING_ID). My problem is that you can't bound two sql data sources and in the buildings query how do I get the value of the ITEM_BUILDING_ID label into the query.

Lets say I have a model Model1 with the property say "IsAccessed". Now lets pass this model to a view using the View("Action1", model1). Now lets say user performs some operation in the View and then submits. Basically a Post happens to an Action "Action1" and the same model1 is passed to the Post Action. Now if I had set "IsAccessed" as true in my get Action of "Action1" and if this property is not accessed in the view ... its getting reset to false. Is there any reason for the same?
