Quick and Dirty:
Note that I have created a constructor for your CustomObj class as
follows :
public CustomObj(int oID, string oName)
{
this.objId = oID;
this.objName = oName;
}
Page code:
---
IList<CustomObj> myList;
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
myList = new List<CustomObj>();
myList.Add(new CustomObj(1, "One"));
myList.Add(new CustomObj(2, "Two"));
myList.Add(new CustomObj(3, "Three"));
myList.Add(new CustomObj(4, "Four"));
Bind();
}
}
private void Bind()
{
ListBox1.DataSource = myList;
ListBox1.DataTextField = "Name";
ListBox1.DataValueField = "BrandId";
ListBox1.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder(50);
foreach (ListItem li in ListBox1.Items)
{
if (li.Selected == true)
{
sb.Append("Text - " + li.Text + ", ");
sb.Append("Value - " + li.Value + "; ");
sb.Append("<br />");
}
}
Response.Write(sb.ToString());
}
