This is very unclear. What is the problem here? You have said "I can add the items" - did you mean "can't"? What is going wrong? Do they just not display or does an error occur? Please update your question using the Improve Question link above.

Thanks,
Ed

An example on ListView is given here http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.listviewitemcollection.aspx#Y3100[^]

In the above example there are two columns, similar to the number of columns specified in the question.

The following code

VB

Dim lv4 As ListViewItem = lvexp.Items.Add(cb_exp.Text)
lv4.SubItems.Add(txt_amt.Text)

added another row in the ListView without any error.

Please see the above example. I think it may be helpful.

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.

C#

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! :)
