Getting Unlikely Html Tags For Hidden Fields

May 8, 2010

I am getting unlikely html tags for hidden fields in my website when redirecting to the page. I do not get it all the time but I am getting it frequently. e.g.: I was support to get

<input type="hidden" name="__EVENTTARGET"
id="__EVENTTARGET" value="" />

but I am getting something like

tyinput type="hidden" name="__EVENTTARGET"
id="__EVENTTARGET" value="" />

and this error is displayed in top of the page.

How To Set Value To Html Hidden Fields

May 23, 2010

I have scenario, where there are html hidden fields, the page can be redirected to itself, with parameters, I have sessions too. Now depending on session value I want to set some hidden values, so that it can be picked up from javascript and can do certain operation. But, the problem is I have no idea about how to get/ set values into html controls using, and also do not know whether this is possible or not. it is imperative that I need some way to hold some data that can be set using and can be picked up by javascript. Since session can not be used for this purpose, so I need some other way.

Set Parameter Value Without Using Hidden Fields?

Jul 6, 2010

I've been using .NET for a little while now. And, I now want to learn to use it the RIGHT way. And, by that, I mean I shouldn't be using hiddenfields on my .aspx page and setting values for those hidden fields in my codebehind. Problem is, I don't know how to ask the question.. so bare with me.. getting a value from a gridview, detailsview, or in this case a DataList when it's bound on a .aspx page, and passing it into my stored procedure? Here's my code of how I do it now..

here's the label for the Department from my datalist, which is on my .aspx page
<asp:Label ID="lblFullDept" runat="server" Text='<%# Eval("FullDept") %>' />

here's the hidden field from my .aspx page
<asp:HiddenField ID="hdnFullDept" runat="server" />

And now for my code behind - where I find the value during the databound of the datalist, and then set the value equal to the hidden field.

Protected Sub dlInfo_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlMnfo.ItemDataBound
Dim lblFullDeptCompare As Label = CType(e.Item.FindControl("lblFullDept"), Label)
hdnFullDept.Value = lblFullDeptCompare.Text
End Sub

And finally, the sql portion, where the value is passed as a parameter...

Protected Sub doInsertActivation()
Dim conn As SqlConnection
Dim comm As SqlCommand
Dim reader As SqlDataReader
Dim connectionString As String = ConfigurationManager.ConnectionStrings("xyz").ConnectionString
conn = New SqlConnection(connectionString)
comm = New SqlCommand()
comm.Connection = conn
comm.CommandType = Data.CommandType.StoredProcedure
comm.CommandText = "abc123"
comm.Parameters.AddWithValue("Department", hdnFullDept.Value)
reader = comm.ExecuteReader()
End Sub

Yes, this works, but I just feel like I need to learn a more efficient way of doing this, as I'm constantly grabbing data and inserting it into sql.

Hidden Fields Data Only Available In A Postback?

Jan 10, 2011

According to MSDN hidden fields section,

In order for hidden-field values to be available during page processing, you must submit the page using an HTTP POST command. If you use hidden fields and a page is processed in response to a link or an HTTP GET command, the hidden fields will not be available.

If I add a HiddenField control at design time and set a value in it at design time or in the Init event in ASP.NET, why would I not be able to read/process the value when a page is first requested?

Web Forms :: Changing Values Of Input Type Hidden Tags - Dynamic Paypal BuyNow Button Using .net Codebehind?

Nov 26, 2010

I have static html paypal buynow button that works great, but it's static.


But it is possible to change the values for the hidden inputs from .net codebehind code? I found this post which takes a different approach of sending these hidden fields instead as a query string to paypal. Not sure I like that though as would this not possiby explose some of those fields like the return page?

Basically what id like to do change the important parts of the button and info I'm sending to make it dynamic.I know I can do something like this in the markup, but that would mean having to fetch data mulitple times was hoping I could somehow adderss the field values directly in the codebehind. Or possibly dynaically generate and insert the entire changing input type fields from the codebehind

<input type="hidden" name="invoice" value="<%= getinvoice()%>">

Possible to add them with something like this: myform.Attirbutes.Add (???). If so how do I contruct these input types in .net?As far as return logic security, I've tested that it's solid, i just need to automate the button process so I don't have to create a buy now page and button for each product.

Why Are Hidden Fields Considered Client Side State Management

Jan 24, 2011

According to MSDN and the MCTS self-paced training, can use Hidden fields for client-side state management. The book material goes on to say view-state is more secure than hidden fields because the data is encrypted. I must be missing something here. I setup a Label and made it hidden. I can store data in this hidden label and it won't even be sent to the client browser. This not only works like server side state (note the runat=server), but this seems more secure than view-state because there's no need for encryption as the client can't even see the field.

<asp:Label ID="Label1" Visible="false" runat="server">secret info</asp:Label>
<input id="Text2" type="text" style="visibility:hidden;" value="secret 99" />

MVC :: Object Properties Get Lost While Posting When Using Hidden Fields In View?

Jun 30, 2010

I am using hidden fields to save some preset data, but upon postback they appear to disappear.

Here's what my controller actions look like:


The view is coded like this:


But when the POST action receives the object back, some of the fields have become null. The FormCollection, however, contains all values. I realize I could just take everything from the formcollection but it's probably better practice to use the object, right?

AJAX :: Hidden Fields In Gridview Inside An Update Panel Not Refreshed?

Jun 22, 2010

I have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.

After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
