hi

if you use web from , you can define runat tag for it below like :

<form id="form1" runat="server">
        <select id="LoESelect" name="LoESelect" runat="server">
            <option>test1</option>
            <option>test2</option>
        </select><br />
        
        
        <asp:Button runat="server" Text="submit" OnClick="Submit_Click"  />
    </form>

and in code behind

 protected void Submit_Click(object sender, EventArgs e)
        {
            var index = LoESelect.SelectedIndex;

        }

Hi fsze88,

Firstly, as vahid bakkhi mentioned, you can set <select> DropDownList with runat=”server” property, and get selected text from its Items collection via the SelectedIndex property.

sval = LoESelect.Items[LoESelect.SelectedIndex].Text;

Secondly, you can also use Request Form collection and name property to access the HTML Select DropDownList selected Text from code behind.

sval  = Request.Form["LoESelect"];
