Best option for visually displaying errors on ASP page via VB code

[Maven4Champ]

Hi all,

I was hoping to get some input on a logical (and most efficient) way to dynamically build a grid (or html table) that displays validation errors that a user might encounter during a validation sub process.

There is no "data source" of where these errors come from but simply a string that I would pass to the grid or table that is descriptive and includes the column there error occured on.

For instance:

For each record
AddRow: resp1 & " cannot be assigned to this user because they are already assigned: " resp2
Next

So as each error is encountered, I display a GridView or HtmlTable for the user on the ASP webpage that adds a row as a row through each loop. Once the page is displayed, they are presented w/ the errors in a Grid or Table so they actually know what the errors are and can resolve them, re-validate and then finally submit once complete.

What is the best way to handle this in VB.NET? As I understand it, a GridView must have a DataSource and this technically doens't have a datasource - thoughts?

Don't think of DataSources in terms of just databases. You could create your own datasource in memory and bind it. I've built pages without any html code or controls--just using response.write to dynamically create html tables. I'm not sure that's the best way however as I'm not a web programmer really, so you might get some better tips in the ASP.Net forum.

Well, I think I now have it working. I used an ArrayList to hold my values and in my FOR EACH loop, added values to the array list. I then call the array list as my datasource for the gridview and guess what - it does work!

I just wasn't sure of the ability of the gridview on this one but it appears to be working fine - thanks for all your help and assistance, as usual!
