Getting value of selected item in list box as string

Question

I am trying to get the value of the selected item in the listbox using the code below, but it is always returning null string.

DataSet ds = searchforPrice(Convert.ToString(listBox1.SelectedItem)); 

Here I am trying to pass the value of selected item as string to method searchforPrice to retrive dataset from the database.

How can i retrive the value of selected item as string?

I am adding items to listbox from combo box which in turn loads the items from the database.

 listBox1.Items.Add(comboBox2.Text); 

Anybody has answer for this..

Answer 1

If you want to retrieve the display text of the item, use the GetItemText method:

string text = listBox1.GetItemText(listBox1.SelectedItem); 

Answer 2

If you are using ListBox in your application and you want to return the selected value of ListBox and display it in a Label or any thing else then use this code, it will help you

 private void listBox1_SelectedIndexChanged(object sender, EventArgs e)     {          label1.Text  = listBox1.SelectedItem.ToString();     }
