What do you do when you can't use ViewState?

由 情到浓时终转凉″ 提交于 2019-12-09 06:01:18
问题 I have a rather complex page that dynamically builds user controls inside of a repeater. This repeater must be bound during the Init page event before ViewState is initialized or the dynamically created user controls will not retain their state. This creates an interesting Catch-22 because the object I bind the repeater to needs to be created on initial page load, and then persisted in memory until the user opts to leave or save. Because I cannot use ViewState to store this object, yet have

I'm new to NCache from Alachisoft. I`m trying to fix the Viewstate very large variable content issue. I have installed and configured NCache Enterprise Edition 4.4.0 (x64) on my server. Changes to web.config and app.browser were done as per instructions: http://www.alachisoft.com/resources/articles/asp-net-performance-view-state-caching.html and http://www.alachisoft.com/ncache/demos/demo-ncache-five-steps-getting-started.html I have successfully created and tested with the "stress test tool" a Local Cache and a clustered Cache called "myCache", one at a time, but without the intended results

What is an optimal value for maxPageStateFieldLength in ASP.NET

由 老子叫甜甜 提交于 2019-12-08 15:54:03
问题 In pages that have a viewstate that spans 10-15KB what would be an optimal value for <pages maxPageStateFieldLength=""> in the web.config in order to reduce the risk of potential truncation leading to viewstate validation errors? 回答1: The maxPageStateFieldLength doesn't limit the size of the view state, so it won't be truncated. What it does is simply control how much of the view state will be placed in one hidden field. If the view state is larger than the maxPageStateFieldLength value the

ViewState invalid only in Safari

由 夙愿已清 提交于 2019-12-08 14:48:41
问题 One of the sites I maintain relies heavily on the use of ViewState (it isn't my code). However, on certain pages where the ViewState is extra-bloated, Safari throws a "Validation of viewstate MAC failed" error. This appears to only happen in Safari. Firefox, IE and Opera all load successfully in the same scenario. 回答1: While I second the Channel 9 solution, also be aware that in some hosted environments Safari is not considered an up-level browser. You may need to add it to your application's

How do I persist the value of a label through a response.redirect?

由 ℡╲_俬逩灬. 提交于 2019-12-08 11:35:33
问题 Here's the situation: I have a label's text set, immediately followed by a response.redirect() call as follows (this is just an example, but I believe it describes my situation accurately): aspx: <asp:Label runat="server" Text="default text" /> Code-behind (code called on an onclick event): Label.Text = "foo"; Response.Redirect("Default.aspx"); When the page renders, the label says "default text". What do I need to do differently? My understanding was that such changes would be done

ASP .NET 2.0 Control State vs ViewState

由 扶醉桌前 提交于 2019-12-08 10:23:10
问题 Is the new ControlState feature only applicable to custom controls or is it available for the standard server controls as well? That is..can you disable ViewState for an entire page with standard controls like Detailsview, Gridview and would it still work? Does ControlState apply to standard server controls? Or in order to work with ControlState for standard server controls you have to modify their behavior by creating a new custom GridView/DetailsView? 回答1: From the Microsoft Documentation.

can't turn off ViewState (asp.net/VS2010), what can be wrong?

问题 I'm working on an application which generates a list of customers from a db. I have disabled ViewState in default.aspx, but now when I viewed the source code of the generated HTML page I saw that the ViewState is on. I've tried to add both ViewStateMode="Disabled" and EnableViewState="False" (separately and even together) without any luck. What can be wrong? ViewState code from the source code if it helps: <div class="aspNetHidden"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET"

问题 I am currently receiving this error: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. I have found multiple solutions to this error. The solution we are currently using is to add a static MachineKey field at the machine level and to use static validation keys and decryption keys. <MachineKey validationKey=""
