protected void Page_Load(object sender, EventArgs e)
{
if (!(IsPostBack)){
lst1.Items.Add("Red");

count = count + 1;


}
protected void btnRemove_Click(object sender, EventArgs e)
{
lst2.Items.Remove(lst2.SelectedItem);

}

}

need help please

help please

your add method adds the selected item to second list box and increments the count variable.. But page level variables loose their value after postback roundtrip cause they are reinitialised every time your page loads.. so your count variable will always hold the value of 0 and when incremented, 1. This wont work...
Why not just use

to get the count of items in second listbox?

is there any remedy if i would choose to use a counter variable? thanks

is there any remedy if i would choose to use a counter variable? just in javascript? thanks
