hi PunithaSabareeswari395,
You need to declare a new object, in this case, a ListViewItem that will hold all the data that has to be added in the Listview and then add it in your listview using AddRange and not Add. This is because, if you use Add only, you pass only one item but if you use AddRange, you can pass as many items as you want
Below is a sample code to solve your problem.
Dim mylists As New ListViewItem(New String() {cb_exp.Text}, -1)
ListView1.Items.AddRange(New System.Windows.Forms.ListViewItem() {mylists})
ListView1.Focus()
Just try this. Hope it helps you! :)
