Each ListItem have properties text, value and selected. Iterate through Items collection and store selected items to database one by one.

If it is not helping, can you be little more specific?

Hi llangelyben,
Thank you for the reply.
Actually my problem is I am dynamically adding items to the listBox. So I donno the 'value' of the text in it. I wanted to get those items like StoreInDb(Items[i]) from the whole list but not the selected item.
But now I chose the second option which is to create a System.Array and store all the text values in it and then put that Array in the iteration.
Here is the code where I used copyTo
Array strArray=Array.CreateInstance(typeof(System.Web.UI.WebControls.ListItem), ListBox1.Items.Count);
ListBox1.Items.CopyTo(strArray,0);
for(int i=0;i<ListBox1.Items.Count;i++)
{
insertIntoDb( strArray.GetValue(i).ToString() );
}
So this method worked but I am still not satisfied becoz Array occupies more memory. If there is any function like ' string ListBox1.getTextByIndex(int index) ' please let me know.
Thank you.

Why not just scan Items collection directly? 


for(int i=0;i<ListBox1.Items.Count;i++) 


{ 


if (!ListBox1.Items[i].Selected)


insertIntoDb(ListBox1.Items[i].Text); 


}
