[eyeseetee]

Hi I was talking about somethign similar on the 2nd page but thought better to start a new post in case no one looked on the 2nd page :) Basically i have a for loop and in it I need to add items to a listbox I have the following but I am getting an error message: foreach (DataRow row in dataSetactorder.Tables[0].Rows) { listboxact.Items.Add (row[0]); } error: " The best overloaded method match for 'System.Web.UI.WebControls.ListItemCollection.Add(string)' has some invalid arguments " any help would be great cheers :)

The error message clear enough. It requires a string type, but you are supplying DataRow. It could be something like

foreach (DataRow row in dataSetactorder.Tables[0].Rows)
{
listboxact.Items.Add (row[0].ToString());
}

I think you are following to my reply for your last post yesterday. In that I haven't meant to use a list box. I was suggesting to use List<string> class. It has a Contains() method and you can take the string easily from it.

Hi!! try the below code for (int i = 0; i <= ListBox1.Items.Count - 1; i++) { if (ListBox1.Items[i].ToString() == TextBox1.Text) { //your statement } }

cheers that sorted my problem thanks!! I decided not to use the string method nav you discussed as I knew the listbox a bit more thanks :)

Why are you not just databinding to the table?
