Hey everyone

Could someone please help ,I've been looking around on google for 2 days now..and I have no luck...:-(

I have at this moment 2 listboxes ...

User selects keywords from the 1st listbox ..

"click add" button ,and the selection value goes to 2nd listbox...I also have a "clear all" button function and a "Clear selected" button function...

That All works fine...but the problem is that I need the 1st listbox to be multi column......example

Keyword | suggested related Keyword (two coulmns)

then add ,clear button functions and a 2nd listbox

Well I've realise that multicolumn is maybe not possible...(well I hope someone can help me...but google is dry on any multicolumn listbox for Asp.net2 web application)

So the Listview......well I'm running on VWD 2005 .net 2 framework..and there's not one for the web application..(I dont want to use .net 3.5 framework)

So what else...Gridview to be the substitute for listbox1 ...so Gridview passing values to listbox and back...But I cant get any codes for this to work like listbox to listbox scenario

to show you what I want please use the following code...(but the first listbox need to be a gridview (or do you have any other ideas of a control) and futher everything needs esle to be the same...functions and the lot

here' my code for listbox to listbox plus function buttons

Jake, I put together a sample that you can use as a start. It's in C#, you can use the telerik code converter or any other code converter to convert it to VB.
