View 2 RepliesTo Save A Variable In Viewstate?
Jun 9, 2010I have searched the web for the answer and saw that mostly variables are saved in viewstate on page.prerender event. Then the value of the variable is set back in page load event.However, when I save a variable in viewstate on prerender or load events, how can viewstate store the value of the variable after it is changed dynamically on codebehind?
Let's say, after page is loaded, user clicked a button which changes the value of the variable in its onClick event. Then the postback event raised since the button was clicked. According to me, the new value should have been lost and cannot be saved in the viewstate if the variable is saved in the viewstate only in prerender event. Because on postback the prerender event wont fire and the value cannot be saved.
Shouldn't I save the variable in the viewstate just before the postback event rises?? If so, how can viewstate store the new value of the variable if the viewstate is saved in prerender event?

View 4 RepliesHow To Save Value Across Postbacks For A Composite Control Without Using Viewstate
Oct 29, 2010I have a composite control that has a couple of private fields that reference values in the cache and these private fields are called during the constructor method. Since a string key is used to identify the value in the cache, I must have a way of storing that string key in such a way that it is available at the time the control is instantiated, and I have to be able to reference it on postbacks without it changing.
In addition, this key is generated the first time the control is loaded, but it should not be changed again after that first time.
How can I accomplish this?
I have already tried saving it to viewstate, but that doesn't work because viewstate is not yet available at the time the control is instantiated.
I have tried using a private field and then checking against Page.IsPostback in the constructor and if it isn't postback, I assign a value to the private field, but on subsequent postbacks it looses it's value, and I can't reassign it in the Page.IsPostBack again because it is an autogenerated GUID.

View 3 RepliesC# - Repeater - Save Data In Viewstate With The Dropdownlist Selection Change Action?
Mar 21, 2011I need some help in the technical approach with the following scenario:-
1) A dropdownlist with some options. It has a postback action on the selectedIndexChange server side event handler. For example, lets say it contains language options such as english, french etc.
2) Repeater with a label and the textbox control. For example label is Emp Name and textbox is containing the Emp Designation. We have to save emp designation in the various languages.
3) Every time i pick something from the dropdown, i have to flip the textbox control and fill the form. Now i want to save the given data of the texbox in the viewstate. So that every time, the user changes the dropdown selection, he can see the repeater data corresponding to the dropdown selection.
4) I guess some kind of relationship between the dropdown option and the repeater data is needed. But how can we make this thing work.
Now which is the best technique to save the data on the server side? I have to keep it in the viewstate.

View 3 RepliesC# - Save A PDF That's Been Streamed To The Browser?
May 19, 2010I'm streaming PDFs to the browser, and it works fine. The problem is when someone clicks the save button. On the same server, we have a "Live" and a "test" site. They are identical, and I've verified that all code is identical. However I'm seeing different dialog boxes when the user clicks "Save"
Test site:
- dialog box: "Save A Copy"
- file name: "Document.pdf"
- file type: Adobe PDF
Live site:
- dialog box: "Save As..."
- file name: "Document.aspx"
- file type: Adobe PDF
To make things even more "fun" I've noticed this behavior ONLY with IE8. With Firefox or Chrome clicking save - regardless of which site (test or live) opens the "Save a Copy" dialog box which allows the users to save the file as a PDF instead of a .aspx file.
