Failed to load viewstate error
-
Hello, I have an ASP.NET form with two
DIVs (both withrunat=server). The first one contains all the controls, buttons and instructions. The second one only contains a success message (just text). In myPage_Loadhandler, I hide the secondDIV, and in myOnClickhandler I hide the firstDIVand show the secondDIVonly if the operation was successful. I had implemented something like this before (not using codebehind the other time, this time I am) and it worked flawlessly. When I click on the Send button, I get anHttpExceptionabout failure to load viewstate. Any ideas? -- LuisR

It may depend on where you are enabling them. I developed a library called "RJContent Panel" (posted as an article here on CP) which dynamically displays a web user control in the specified content area of a template page. I kept getting load viewstate errors if I would create the dynamic control in the page load after the Init. When I switched the process to the Init, it was all okay. I believe the postback should have the same controls available as when the page was created in order for the viewstate to load properly. Rocky <>< Opps.. Here you go!

DIVwith the form, and make visible theDIVthat contains the success message. If an error occurs, the form is kept visible and an error message is displayed. (edit) TheDIVis hidden in thePage_Loadhandler, and it works well, the first time only the controls appear and not the success message. When I click the Send button, the exception is thrown, I believe, when I try to hide the controls'DIV, or later when the form is trying to reload the viewstate and it can't find the controls.(end edit) What is driving me nuts is that I did this exact same thing in a reusable contact form (which contains its code in the same.aspxand not in a codebehind.csfile) and it works perfectly. Thanks for your reply, -- LuisR

If you can post some code (simply test app) that fails, I can look at it and see what the problem is. Rocky <>< Oh ya.. Here you go![^]
