What database are you using? OLE is slow but may be your only choice.

Also use a reader (forward only cursor) instead of a DataTable, it's faster for this kind of scenario.

But, consider the...

greeny_1984: Well that would just exhibit the same behaviour as whats currently happening. But you're on the right track.

Image buttons are rendered as type="submit" which means when you press the...

Aha, you are using a strongly typed DataTable.

You must be handling the DBNull somehow otherwise you would be getting an exception when populating the table.

Have you tried just == null ?

Hmm... well it works for me. You'll have to post some code or give more information.

Dont have the radio button in the control. Use a repeater to render radio button, user control pairs.

You need to compare the column value with System.DBNull.Value

So assuming a DataTable for example:


if( myDataTable.Rows[0]["someColumn"].Equals(System.DBNull.Value) )
{
//Handle...

Wow! well how you can read 15 hours of ASP.NET getting started and surmise that merely changing the file extension of an HTML page is all that's required seems improbable.

But what the hey. Ok you...

The problem is you haven't researched ASP.NET properly.

Use Google (or your favourite search engine) to search tutorials like this:

You can disable viewstate for the page so the controls don't keep their values between postbacks.

Usually in ASP.NET you don't cross post to different pages like in the classic ASP days. With ASP.NET the form POSTS to itself by default. So you don't need a re-direct unless you need to go to...

I can't understand why you can't get web controls to appear on the page. Can you post some code?

p.s. Do you know about the empty data template?

I've replied in your other thread.

How are you 'Browsing' your ASP.NET app ?

You don't need IIS if you have Visual Studio 2005 Express Edition (any edition 2005+) It includes a web server. When you run the app from VS (F5 to debug, or Ctrl+F5 to run without debugger) it...

Well that's what 90% if the software world is using. Hell I'm still maintaining Framework 1.1 projects.

Back in the time of classic ASP, one day I found myself conactenating <tr> <td> tags in a...

Why would you not use the web controls?

Look at the System.Web.UI.HtmlControls namespace there's HtmlTable objects and HtmlTabkleRow and HtmlTableCell, just foreach your DataTable into HtmlTable...

Use ADO.NET to get data from the database.

I recommend you create a custom class that has a property for each of the data columns. Iterate the database resultset (be it a SqlDataReader or...

Just compile the website and upload only the .aspx files to the web server. The cs files are not required all the code in the .cs files is compiled into the single .dll in the bin folder.

Whichever one you want to be the main page. It's only for debugging anyway so that VS knows which page you want to start the app at.

This is probably to do with how the javascript is rendered (somewhere in the middle) in the completed page that goes to the browser.

I would put the javascript in a .js file. Then in the page_load...

You have a couple of choices depending on how many elements you require to print. There is no 'builtin' solution for this kind of thing in ASP.NET

look into CSS

I'm not certain of what you require. But perhaps you need DBNull.Value this represents a null database value. For example you can comapare a value in a DataSet to DBNull.Value which returns true if...

Use ExecuteScalar() on the command object it is very efficient, returns just the first value in the first row of the result set. No need for an expensive DataAdapter and DataSet.

You'll have to expand on this, I'm not understanding it I'm afraid. In it's default config web controls on aspx pages keep their own data anyway via viewstate, is this what you're on about?

ASP.NET is a web technology which is 'pull' only. A webserver can't 'force' your browser to browse it cos there's an urgent appointment to be seen.

All public IP's (all the ones on the internet) are registered to someone or organisation. You can look them up using Who Is.

Yes but it's not trivial, and you have to have sufficient authority to get it legally.

You can't hide your IP. You can use a different IP owned by a proxy server. Most ISP's host a proxy server. Using proxies is commonly referred to as hiding your ip but that is a misnomer you are just...
