View 1 RepliesI have a page with two forms on it. The first form is a "Search" form and does not have the runat="server" attribute. It is merely meant to post some search criteria to another page on the site. The second form is the standard "aspnetForm". Inside that form I have a ModalPopupExtender... Within the ModalPopupExtender there are two buttons that should postback to the server when they are clicked by the user. My problem is that when the buttons are clicked the page posts back to the "Search" form... The only clue I have is that if I move the form to the bottom of the page (after my ModalPopupExtender), everything works fine. It seems that the extender uses the first form it can find on the page. Is there anyway to force it to postback to the correct form?

I have a user control I am adding dynamically. It has a link button and a text area on it. The containing div is hidden via style sheet (client side), and I use some jquery to pop it up in a modal. It is getting added in the init and the button click event is firing on the server. BUT the textareas value is not being set. On further inspection the field value is not even being sent in the form POST data. why the value is not being sent. The rest of the form values are being sent with no problems.
View 1 RepliesI'm posting data to a page called process.aspx that handles some business logic with the following code:
<%@ Page Language="C#" %>
<%
MyData.process(Request);
Response.Redirect("")
%>
this page I will be calling from a variety of pages. Is there some way of knowing from which page my form was submitted? I was thinking something along the lines of writing:
<form id="frmSystem" method="post" action="process.aspx?page=<%= %>">
However I don't know what to write in between the <%= %> to get the current page name.
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?
View 7 RepliesSo I have a page to edit employees.
Here is my view model:
[code]....
I'm not sure why this is happening. The dropdown is loaded correctly when I navigate to the page, but not when the view is redisplayed.
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 have a form as
<form action="" method="post">
<input name="Descripcion" type="hidden" value="" id="Descripcion" runat="server" />
<input id="Submit1" type="submit" value="Comprar" />
Instead of clicking on submit button i want that the form should be posted without clicking submit button with hidden fields
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.
View 1 RepliesI want to disable my viewstate in a form because its too bulky (about 1mb per page) due to retrieving some data from database and in other place on the same form I want to access a control from my master page. but when I set viewstate of Listview to false I'll get following error: Object reference not set to an instance of an object. what should I do in this situation? veiwstate is too damn bulky
and here is what I've written for accessing particular control:
Control cc = Page.Master.FindControl("mainContent").FindControl("ListView1").FindControl("itemPlaceholderContainer");
foreach (Control ListItemctrl in cc.Controls)
{
Control lblNewsId = ListItemctrl.FindControl("lblNewsID");
if (lblNewsId != null)
{
Type t = lblNewsId.GetType();
if (t.FullName == "System.Web.UI.WebControls.Label")
{
string newsID = ((Label)lblNewsId).Text;
foreach (Control childCtrl in ListItemctrl.Controls)
{
CheckBox ctrlCB = childCtrl.FindControl("chkItem") as CheckBox;
if (ctrlCB.Checked)
{
//based on DDLAction we will do the things ;)
}
if (childCtrl.FindControl("chkItem") != null)
break;
}//end foreach childCtrl
}
}//end outer if
}//end foreach listItenctrl
I know this question has been asked million times but I think my situation is different here.I am using .NET Framework 3.5 SP1, there is no form action on the page and it's not happening when I try to submit the form quickly. I am not on a web farm either.I have a page with two GridViews. One Gridview acts as a master gridview and second as detail gridview. First Gridview has autogenerate select button and clicking select would bring related records in detail gridview at the bottom. I have a refresh Link button at the top. Everything works fine. I click refresh button and it works fine too.Ok when problem start happening when I leave the page idle for like 10 minutes or so and then I click Refresh button only then I get this "Validation of Viewstate MAC failed" error.
View 1 RepliesI have an ajax form that has a simple click event. Inside the click event, at the end of the method, I have a Response.Redirect back to the same page. For the purpose of this thread, I will leave out the reasoning of this (it is just something that I had to do). Once the ajax call is complete and the redirect takes place, all of my default control viewstates get wiped out. The thing that doesn't make sense, is that if I define my own ViewState right before the Response.Redirect, these ViewStates also get wipedout. So, my question is, do ViewStates only hold their values after one postback/refresh? And, is there a way to use ViewState with the method described above? I am being forced to use the querystring to pass parameters.
View 2 RepliesI have a sample page called Redirect.aspx with following content;
<body onload="document.forms.container.submit()">
<form id="container" runat="server" method="post" name="container">
<input type="hidden" value="<%=Request["APP_ID"]%>" name="APP_ID" />
</form>
</body>
the Page_Load method is following:
protected void Page_Load(object sender, EventArgs e)
{
container.Action = Configuration.Instance.PageToRedirect;
}
To this Redirect.aspx page, I'm directed from some external page. In the request context, I have APP_ID key, which is passed from this external page. Next, I want to pass this APP_ID value using POST to some other page, which is defined in the configuration. Unfortunately, I'm getting such error while redirecting:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
I don't want to disable view state validation (<pages enableViewStateMac="false">) because this is not the "solution" I want to apply.
Besides I don't understand why I'm getting such an error. Can someone get me through this ? Is there any other way to automatically submit a form on Page_Load event ?

View 1 RepliesI 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:

My ViewState implementation causes "Confirm Form Resubmission" dialog to appear each time I press 'back' button, but when I create test site using microsoft's aspx their viewstate isn't causing such problems. What should I know to prevent my browser from showing "Confirm Form Resubmission"? I've found an interesting resource here, the problem described in terms of browser caching, if the page is cached than it won't make a post at all, now it is interesting how to make my page cachable by default.
View 2 RepliesNow here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:

I have problem getting values from viewstate in GetTopThemes.

when the page is not Posted back, I saved all values in the viewstate.
I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.
what is crosspage posting?
View 3 RepliesSo I have a form with a text area on it, and I need to post it. I can't encode it (as far as I know) client side, prior to submit, and it causes the yellow screen of death before reaching the HttpPost action handler.
