State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?
Mar 23, 2011I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.
I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.

Web Forms :: Setting A Hidden Field From The Master Page?
Jul 13, 2010From the master page of my ASP.NET site I need to set the value of a hidden field in every get and post request and then subsequently read it in the next request.The problem is that in the post request the code works fine but when the client sends a get request I am unable to read the value of the hidden field from teh Master Page. Is the hidden field the proper approach to this and if so how do I read the value set in the hidden field in the subsequent get request. If the hidden field is not the proper approach for this then what else should I use?

Page Load Event - Get UserId From Db And Put Into Hidden Label Field?
Jul 30, 2010I am working on Scott Mitchell's ASP.Net in 24 hours book. I am running into what looks like a simple problem that is getting the best of me.
When a page loads, the UserId of the currently logged in user will be retrieved in the page Load event and placed into the Text value of a Label. But, when the page opens when I am running the app, I am getting an error in the lower left corner of the browser. When I open up the error message, I see this:
Webpage error details
Message: 'UserIDValue' is undefined
Line: 92
Char: 1
Code: 0
URI: http://localhost:51035/PhotoAlbum24hrs/PhotoAdmin/ManageCategories.aspx
Here is the web page's Load event (VB) code:
[Code]....
Here is line 92 and the surrounding lines from the page source when I run the app:
[Code]....
This matches what is in Scott's book. (Or else I have been looking at it too long and have missed something.)
If I make the UserId Label visible, I can see the logged in user's ID displayed on the page. So, what is going on here? Why am I getting this error?

Forms Data Controls :: Grid View - Can't Get The Value Of An Hidden Field's Footer Row
Dec 3, 2010I can't get this to work:
I have a grid view with several TemplateFields. A couple of them are set to Visible=False; each template field has an EditItemTemplate, an ItemTemplate and a FooterTemplate.
[Code]....
While in GridView_RowUpdating event, the value bounded to the EditItemTemplate is properly read
[Code]....
so, debugging ttbImp.Text = "4"; But when trying to get the value bounded to the FooterTemplate, the label contains no values.
[Code]....
so, while debugging, lblImp.Text = "";
why that? I believe it has to do with the hidden visibility of the field, but I can't understand why it reads the value inEditItemTemplate, and it doesn't in FooterTemplate.
