Take a look at the ListBox control to allow multi-select.

<asp:ListBox runat="server" ID="lblMultiSelect" SelectionMode="multiple">
            <asp:ListItem Text="opt1" Value="opt1" />
            <asp:ListItem Text="opt2" Value="opt2" />
            <asp:ListItem Text="opt3" Value="opt3" />
</asp:ListBox>

in the code behind

foreach(ListItem listItem in lblMultiSelect.Items)
    {
       if (listItem.Selected)
       {
          var val = listItem.Value;
          var txt = listItem.Text; 
       }
    }

If you are using a ListBox control and LINQ you can try this:

Code Example:

control.Items.Cast< ListItem >().Where(x => x.Selected).ToList();

I hope this solves your issue!

In that case you should use ListBox control instead of dropdown and Set the SelectionMode property to Multiple

<asp:ListBox runat="server" SelectionMode="Multiple" >
  <asp:ListItem Text="test1"></asp:ListItem>
  <asp:ListItem Text="test2"></asp:ListItem>
  <asp:ListItem Text="test3"></asp:ListItem>
</asp:ListBox>

For multiple selection dropdown list,cannot accomplish it directly using dropdown..Can be done in similar ways..

Either you have to use checkbox list or listbox (ajax inclusive)

Dropdown list wont allows multiple item select in dropdown.

If you need , you can use listbox control..
