Hi,

In my C# Windows Form MyForm, there's one ListView control listView1 in the
MyForm.
The ListViewItem in the listView1 MATCHING EXACTLY the data in a SQL Server
database table Customer.
e.g.,
Serial ID Name
----------------------------
1 123 John
2 125 Marry
3 201 Leo
4 305 Britney

If we DELETE the first Row [1,123, John] in the listView1,
How we will reasign the Serial for the rest Rows.

the result:
Serial ID Name
----------------------------
1 125 Marry
2 201 Leo
3 305 Britney

Can Any One Give Nice Idea For Reasign the listview Serial No?

I think you didn't get what I was trying to do. For example: I have 10 rows in the listview, and in column serial no rows goes from 1-10. Suppose I remove rows 4,5,6 from the listview, the remaining rows left like this 1,2,3,7,8,9,10.

What I want is the numbers of rows reset automatically. Instead 1,2,3,7,8,9,10 I want the numbers to be automatically reset to 1,2,3,4,5,6,7 without effecting the other columns. Can you please try with my code ????

C#

private void RemoveSelectedItem_Click(object sender, EventArgs e)
{
    if (TbSearchDCNo.Text != "")
    {
        Connection();
        ListViewItem item = listView1.SelectedItems[0];
        cmd = new SqlCommand("delete from DeliveryChallan where SNo='"+item.SubItems[0].Text+"'", cs);
        cmd.ExecuteNonQuery();
        listView1.Items.Remove(listView1.SelectedItems[0]);
        for (int i = 0; i <= listView1.Items.Count - 1; i++)
        {
            listView1.Items[i].Text = (i + 1).ToString();
        }
        GrandTotalCalc();
        listView1.Refresh();
        listView1.Update();
        BtnDcModify.Focus();
    }
    else
    {
        listView1.Items.Remove(listView1.SelectedItems[0]);
