Hi,

Please use following code for trimming comma:

C#

string strSelected = string.Empty;
foreach (ListItem item in ListBox1.Items)
{ 
    if (item.Selected)
    { 
        strSelected += item.Text + ",";
    }
    strSelected = strSelected.TrimEnd(',');
    
}
com2.Parameters["@ListBox1"].Value = strSelected;
