I am working on a website for a company who wishes to upload images. Preferably the images would be displayed as thumbnails and the of course when someone clicks on the thumbnail, the image would be displayed. Does anyone know of a software product that will work with Asp.net to manage images and display them as thumbnails. I imagine I could code this on my own, but I don't want to re-invent the wheel. Thanks in advance for the help.

I am still pretty green with ajax controls so forgive me if this is a silly question. I have a GridView control inside of an UpdatePanel that is inside of a ContentPlaceHolder in a ContentPage. When I click on a page number to change the page and the grid reloads, actualy any action that causes the GridView to reload using the update panel causes the grid to take on the background color of the body which is defined for the Master Page. The first time the page loads I see the GridView just fine with the back ground image behind it for the ContentPlaceHolder but after partial...State Management; .Net Profiler

I have a radiobutton list in a gridview. On selected index change, I place the row in edit mode. The problem is that when the row goes into edit mode, I lose the selected value of the radio button. Any idea what could cause this?
you don't tell too much about your case so I assume it is the following.
When you change the grid to edit mode, you re-databind it. And when that happens on postback event (after Page_Load), the created control (e.g databinding creates contros based on template) cannot load postback data anymore. I've explained this in with an...Losing session state after postback
I have a webform with two listboxes. One is the parent and the other one is the child (meaning the child listbox gets populated depending on what is selected in the parent listbox).
I have one dataset that has four related datatables in it. This data gets loaded during the Page_Load event. The child table in question, has 7 records in it, of which I need to filter out a smaller subset. I tried using the DataView, which was successfull, but I needed to save this filtered data across postbacks, and you can't save a dataview in session state because it's not serializable. So, I made a copy ...lose image src on postback

No I'm not. I thought viewstate was enabled by default for all server controls.
Do you set the initial src from
codebehind? Inside an if Page.IsPostBack equals false test or not? Is
the image inside a form tag with runat=server? If not, you have no
my listboxes arent remembering their state on postback. i can understand why. yet posting back every time a user wants to move an item is not an option either.
You need to use a hidden input as a helper field to persist your client-side changes. This will allow you to resbuild the ne...DropDownlist in Gridview lose data during postback
