            for (int i = 0; i < ListBox1.Items.Count; i++)
            {
                if (ListBox1.Items[i].Selected)
                {
                    string selectedItem = ListBox1.Items[i].Text;

                }
            }
        }

Its upto your design of database. You can store the data in multiple ways.
One way , you can put the multiple rows according to the selection.
Or you can also save it using some separator like comma in a single row.

To get selected items Iterate all the items in listbox and find all the seleced elements using the selected property of listitem. Now according to your design, you can save one by one, insert it in database in one go.

Hi,

Try this-

HTML-

<asp:ListBox ID="ListBox1" runat="server" SelectionMode="Multiple">
    <asp:ListItem Selected="True" Value="1">a</asp:ListItem>
    <asp:ListItem Selected="True" Value="2">b</asp:ListItem>
    <asp:ListItem Value="3">n</asp:ListItem>
</asp:ListBox>

Code-

var selected = ListBox1.GetSelectedIndices().ToList();
var selectedValues = (from c in selected
                      select ListBox1.Items[c].Value).ToList();

public string GetListBoxSelStringInComma(ListBox Listbox1)
{
string selectedItem = "";
if (Listbox1.Items.Count > 0)
{
for (int i = 0; i < Listbox1.Items.Count; i++)
{
if (Listbox1.Items[i].Selected)
{
if (selectedItem == "")
selectedItem = Listbox1.Items[i].Text;
else
selectedItem += "," + Listbox1.Items[i].Text;
}
}
}
return selectedItem;
}
// This Function Will Return all the selected values of Listbox in a string
 seperated by comma

See the last post in this[^] thread.

string q = "select ReqItemNo, BalanceOnStock from Product where ProHead ='" + DDLItem.SelectedItem.Text + "'";
        cm = new SqlCommand(q, cn);
        SqlDataReader r = cm.ExecuteReader();
        while (r.Read())
        {
            
            LBox.Items.Add(r.GetString(0));
            LBoxShow.Items.Add(r[1].ToString());
            foreach (ListItem lboxItem in LBox.Items)
            {
               abc = Convert.ToInt32(lboxItem);
                foreach (ListItem lShowItem in LBoxShow.Items)
                {

                    dal = Convert.ToInt32(lShowItem);
                }
                showdata = (Convert.ToInt32(dal) - Convert.ToInt32(abc) * Convert.ToInt32(TxtWorkSelection.Text));
                              
            }
            
        }

                {

                    item.Text = lstEmployees.Items[i].Text;
                    item.Value = lstEmployees.Items[i].Value;

        }

Happy Coding..

for (int i = 0; i < chkgrouplist.Items.Count; i++)
        {
            if (chkgrouplist.Items[i].Selected)
            {
                query =chkgrouplist.Items[i].Value ;
               
            }
        }

//window ListBox
for (int i = 0; i < DocsListBox.Items.Count; i++)
{
if (DocsListBox.GetSelected(i))
{
string selectedItem = DocsListBox.GetItemText(DocsListBox.Items[i]).ToString();
//insert command
}
