Using Vb.Net 2003 Asp.Net 1.1
I have a dynamic data bound drop down list, when the user selects thier selected item I have to use the autopostback feature.
Problem is: when the page comes back it is at the top of the page not where i have the control.
I don't really need it to focus back on the dropdownlist but to scroll to it, I want to do it in the code behind.
Any "New" ways to do it, I mean new as in code from like 2010 instead of old code from the early days.
I really don't want to use Page.Register new Script...... code if I can avoid it.
What would be cool is a ScrollToControl() Function for my code behind that worked but didn't register script.

I have 3 drop boxes: 1.) Choose Operation 2.) Choose Site 3.) Choose Area. All three of them are linked to an SQL server database which has 3 tables following the same heiarchy of order. I.e. Areas belong to a Site and Sites belong to an operation. And there can only be one operation per site, or one site per area.
First you select an operation, then the page auto postbacks to filter the sites. Then you pick a site and again it autopostbacks to filter the areas. The issue I am having is that when an associated operation has no sites underneight it, and therefore no areas under that, the previous values that were in the boxes are displayed and the user can't click on the boxes anymore. I think this is kind of cheap looking and would like a way to make it so the boxes are clear (i.e. nothin in them). Is there anyway to check if they are going to freeze like that and assign them blank values?

I have a page where in there are various entry fields like name, registration number, country, state etc whcih are mandatory. On selection of country in dropdown,the state dropdown is filled and in the phone number boxes the country code is also filled simultaneously.
When I click on Save button it shows the required fields respective messages in the validation summary. When I select the country the state and country code are filled and the validation summary vanishes though I have not entered text in the other mandatory fields. None of the required fields messages are displayed though all fields except Country state and country code are filled.

I have a Range Validator as follows. It is for restricting values between 1900 and 2070. However, it fires error when I enter a alphabet also. I want this to be fired only if the user enters integer values. How do I overcome it?
<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="txtYear"
ValidationGroup="report" ErrorMessage="EM1|Year" MaximumValue="2079" MinimumValue="1900"
SetFocusOnError="True" Display="Dynamic" Type="Integer">
<img src="../../Images/error.gif" alt="Format" />
</asp:RangeValidator>

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I have a couple of textboxes (actually a set of pairs of textboxes) where users can either enter a value or a percentage of a value but cannot use both. So in any given time some of these textboxes are disabled depending on which option the user chose.
For the textboxes representing percentages, there is a range validator to make sure only values from 0 to 100 are entered. If user selectes to enter datanot in percentage form, the percentage textbox gets filled automatically based on the value user enters. So if the total is something like 8 and user enters 2, the corresponding percentage textbox gets filled with 25% (minus the % sign).
However, the vaidation fails as if there is nothing there, persumably because the textbox is disabled. How do I get around this?

I have a very odd and disconcerning problem. Just recently a page where I have 1 textbox and a buttoon has ceased to work.
When I look at the post coming into the PageLoad, the pageType is "POST", but the Page.IsPostBack is false!! and the textbox (which had content) is empty.
I have stripped all AJAX script out, so I have a very vanilla page (in a master page) being served.
The pages is
