viewstate

问题 I have a Wizard to Add an Employee from my org. In Step1, I have few controls, one of them is EmpID (PK). The problem arrives in Step2, where I have only one control that is DropDownList1 which is binded from Datasource (code-behind). I want this value of DropDownList1 and EmpID from previous Step to insert it into another table called 'dbo.Emp_Skills'. 'dbo.Emp_skills' table has 2 columns: EmpID (FK) | SkillID (FK) How do I insert value of EmpID into this table when it is not actually saved?

问题 I develop mostly for desktop so, I tend to think as WebForms as a web equivalent of WinForms. Unfortunetly this is not true. Recently I have discovered that the Viewstate have some kind of timeout. My problem is similar as I have read in most questions, in particular here (in my case is only around 5 to 10 minutes). Here Microsoft says that one solution for this problem is: <asp:Page EnableViewStateMac="False" /> However as we can read further they say: Security Note: This attribute should

问题 Using JMeter, I'm attempting to log in to an asp.net web forms application. I recorded the login sequence to a *.jmx file, and now I'm attempting to extract the __VIEWSTATE, __VIEWSTATEGENERATOR and __EVENTVALIDATION hidden inputs using the Regular Expression Extractor post-processor. In all 3 cases JMeter is extracting the name of the variable that I want to extract into (eg "${viewstate}") instead of the value I want to extract. Here is what the RequestBody looks like when I look at the

问题 I am using third party server-side controls on my website (Telerik RadControls for ASP .NET). The menu control has a complex structure which is bloating the size of the viewstate affecting load times. I am not aware of the details of viewstate except that it is used by the web server to keep track of control values. Since most of the pages on my website are display only, is it possible to disable the viewstate where user input is not taken? All dynamic items are being regenerated on page load

问题 I have a form wherein I populate content using stored procedure and I perform update actions on the content. Now my update button works fine. My problem is that each time I click on 'refresh' button in IE, the content gets updated and I don't want that to happen. I am new to .Net and all this ViewState stuff. Any help is appreciated.. Here is my code: public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } public void BindGridView() {

问题 I have a Panel on my Page: <asp:Panel ID="pnlTest" runat="server" /> Then I dynamically add a TextBox to it on Page_Load: TextBox simpleTextBox = new TextBox(); pnlTest.Controls.Add(simpleTextBox); simpleTextBox.ID = "SimpleTextBox-1"; Is there a way to pull in the information typed in this TextBox without pulling it directly from Request.Form? I thought I could do something like this after I added it again: lblPresentResults.Text = myTextBox.Text; I know this example seems contrived, but I

问题 I've been learning about MVC for a while, and I think I pretty much understand what it's all about. But there is one thing I don't yet understand: I keep hearing with MVC that there is no viewstate nor postback. Can someone explain what this means in simple terms? 回答1: Try this SO answer which addresses the same question. Extra info after comment/question: ASP.Net web forms can use viewstate to store the state of server controls on the page and to manage invocation of server side events such

问题 I'm creating user controls that i will put into an update panel and make them visible only when required using triggers. Once visible it will float in a dialog box so it has a close button which will just hide the control on client side. The controls have multiple post back states, like a wizard, i'm using a multi view control to accomplish that. My problem is that once the user is at step number two in the control, if the user closes the dialog, than opens the dialog again, (note that the

问题 I'm considering using an ObjectDataSource as an intermediate between my page controls and my data access layer & object model. Traditionally I have manually created the object and populate it via a series of findcontrol statements when I need to insert/update data in the database. I'm hoping that I can use the ObjectDataSource to marshal data between my object and my controls, eliminating that manual code, as long as the ObjectDataSource doesn't come with a lot of overhead. I noticed the

问题 I am trying to simulate a form submission on an ASPX.NET site. The flow of the website when accessed in a browser is as follows: 1) In a browser the user visits http://mysite.com/ which is configured with Basic Authentication 2) Upon correct credentials, the user is shown a form with one input text box and a button (URL stays http://mysite.com/ but the form being served is Default.aspx) 3)User enters some text and presses submit... 4) The page reloads... URL is still http://mysite.com/... but
