问题 When I disable ViewState for the page. It does not allow any other control to use ViewState .. even if I set EnableViewState="true" for that particular control .. is it possible to enable ViewState for a control when ViewState is disabled for the page itself? if not how can disable viewstate for controls on page except for few without specifying EnableViewState="false" explicitly .. typing the same into so many controls is hectic .. 回答1: If you set turn page's ViewState off, then there is no

问题 So i am trying to save a variable in the viewstate and use right after the button is pressed. The problem is that you have to press a botton 2 times before something is written. This code is the problem as i see it boilde down to the basics. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <asp:Button

问题 Where can I see the total size of ViewState out of the total size of the Response (value in bytes in the Body column) in Fiddler 2? Thanks! 回答1: You could simply copy-paste the value of the __VIEWSTATE hidden-field (using "view source" in the browser, works without fiddler) to a new text-file and check the size of this file. 回答2: There is a very nice plugin for Firefox that allows you to directly see the size of the viewstate in your browser: Firefox Viewstate Size Plugin 1.0.3. 回答3: You can

Bug in Label ASP.ViewState implementation?

由 ♀尐吖头ヾ 提交于 2020-01-15 09:21:06
问题 EDIT 2: Well, I went to the code. Note what they are doing here. They are saying load viewstate, and then turning around and setting the Text property to what was in the viewstate. After LoadViewState is called though viewstate tracking is on, and that results in the behavior I'm seeing. I think what the code should say is: if (s != Text) {Text = s;}. That would get rid of the issue altogether and keep whatever invariant they need in place. /// <internalonly/> /// <devdoc> /// <para>Load

Persisting variable after AsyncFileUpload call to OnUploadedComplete

由 半城伤御伤魂 提交于 2020-01-15 06:46:12
问题 This is a strange one. So I have an Ajax Toolkit file uploader called AsyncFileUpload located in an update panel. This AsyncFileUpload control, as soon as you put a file there, begins to upload it and calls the server. I then store this file as a BLOB and obtain the row ID from a database table using SELECT @@IDENTITY. So far so good, I now have a row ID and I wish to store it. I placed it inside a hidden field but when AsyncFileUpload calls OnClientUploadComplete, hidden field is blank! So I

How to prevent JSF2 injection of hidden javax.faces.ViewState

由 末鹿安然 提交于 2020-01-14 05:20:33
问题 How can I disallow Mojarra, injecting a javax.faces.ViewState hidden into my <form> s? I have a search <form method='GET'> which works first time my page is loaded (because my view-scoped bean is re-initialized correctly). But after an AJAX pagination in the page (over a PrimeFaces grid), Mojarra (or PrimeFaces?) injects a hidden javax.faces.ViewState into my form. Now when I submit the form it doesn't restart my view-scope bean because of javax.faces.ViewState input. The issue here is: I
