                <div class="col-md-12">
                    <asp:DropDownList ID="ddlCompanyName" runat="server"
                        CssClass="form-control btn-group"

                        OnSelectedIndexChanged="ddlCompany_SelectedIndexChanged">

                        <span class="glyphicon glyphicon-font"></span>
                    </asp:LinkButton>

                </div>
            </div>
        </div>

And the code behind...

protected void ddlCompany_SelectedIndexChanged(object sender, EventArgs e)
{
    txtCompanyName.Text = ddlCompanyName.SelectedValue == "-1" ? string.Empty: ddlCompanyName.SelectedValue; 
    btnCompanyText_Click(this, EventArgs.Empty);
}
protected void btnCompanySearch_Click(object sender, EventArgs e)
{
    Search(false);
    ddlCompanyName.Focus();
}
protected void btnCompanyText_Click(object sender, EventArgs e)
{
    Search(true);
    txtCompanyName.Focus();
}
private void Search(bool bVal)
{
    txtCompanyName.Visible = bVal;
    btnCompanySearch.Visible = bVal;
    btnCompanyText.Visible = !bVal;
    ddlCompanyName.Visible = !bVal;
}
