Store Data with ArrayList using ASP.NET 2.0 and VB.NET

This tutorial will show you how to store data with ArrayList using ASP.NET 2.0 and VB.NET.

At first, you need to import the namespace from System.Collections. The System.Collections namespace contains classe ArrayList which Implements the IList interface using an array whose size is dynamically increased as required.

Imports System.Collections

We migrated our web sites to Server Intellect over one weekend and the setup was so smooth that we were up and running right away. They assisted us with everything we needed to do for all of our applications. With Server Intellect's help, we were able to avoid any headaches!

In order to run the example, we will use the btn_get_Click to trigger the task. The code as following:

Protected Sub btn_get_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btn_get.Click

Dim name As String = String.Empty
Dim EmployeeList As ArrayList = New ArrayList()
name = "Jake"
EmployeeList.Add(name)
name = "peter"
EmployeeList.Add(name)
name = "lily"
EmployeeList.Add(name)

Me.GridView1.DataSource = EmployeeList
Me.GridView1.DataBind()

End Sub

We moved our web sites to Server Intellect and have found them to be incredibly professional. Their setup is very easy and we were up and running in no time.

The front end StoreDataWithArraylistVB.aspx page looks something like this:

<tr>

</tr>
<tr>

</tr>

</table>
  
</div>
